logarithm solver

Let us solve problem using logarithm solver

Solve for x: 5x = 2.
Apply the logarithm of both sides.
log 5x = log 2
Use theorem 2 to simplify the equation.
x * log 2 = log 5
Solve for x by dividing each side by log three
x = (log 5/log 2)
A decimal approximation may be found if desired -
x = 2.32192809.
Solve Log3(2x+5) = 2 for x.
Write an equivalent exponential expression, 2x+5= 32
2x+5=3*3
2x+5=9
Solve for x. 2x=4, x = 2.

equivalent fractions calculator

Let us solve problem using equivalent fractions calculator

Convert 9.6 to equivalent fraction number by using equivalent fractions calculator
Here transfer 9.6 to an equivalent fraction,
Multiply both the numerator & the denominator by 10.
= (9.6 x 10)/10
= 96/10
Hence there is one digit in a place of the very last digit is the "10th" decimal place. Therefore we can just say that 0.1 is the same as 1/10.
= 9.6 can be written as the equivalent fraction = 96/10

maxima and minima

Let us learn about maxima and minima

A function is refers to be monotonic if it is either increasing or decreasing but not both in a given interval.
Consider the function f(x) = 3x+1, x£ [0,1]
The mentioned function is increasing function on R. Hence continuous function is a monotonic function in [0, 1]. Continuous function has its minimum value at x = 0 that is equal to f (0) =1, has a maximum value at x = 1, that is equal to f (1) = 4.
'Every monotonic function imagines its maximum or minimum values at the end points of its domain of definition.'
Point to be remember that 'every continuous function on a closed interval has a maximum and a minimum value
The maxima and minima value of an expression or quantity is meant primarily the "greatest" or "least" value which it can receive. However, there are notes at which its value ceases to increase & begins to decrease; its value at such a point is known a maximum. So there are points at that its value ceases to decrease & begins to increase; such a value is known as a minimum. There may be many maxima or minima, & a minimum is not necessarily less than a maximum. For illustration the expression (x 2 -1x+ 2)/(x - 1) can driven all values from - 00 to - 1 & from + 7 to + oo, but has, so long as x is real, no value between - 1 & + 7. Here - 1 is a maximum value, & + 7 is a minimum value of the expression, though it can be made greater or less than any assignable quantity.

decimal squares

Let us learn about decimal squares Decimal Squares is a program for tutoring place values & the use of decimals. Decimal Squares was improved by Professor Albert Bennett at the University of New Hampshire. The bulk of the program is a series of classroom learning materials & books that are available for purchase. 1 aspect of the Decimal Squares program which you can access for free is the games section.

The games section of Decimal Squares offers 8 interactive games which students can use to develop their understanding of place values.
Decimal Squares are applied as a visual model for the part-to-whole concept of decimals & for illustrating decimal equality, place value, inequality, & estimation.

graphing fractions

Let us learn about graphing fractions


The term 'fraction defines a number that is being used to describe a part of a group & while writing it student can use the term denominator & numerator. Nominator is used to write the number that is above the line & denominator is used for the number that is below the line. Best example: If you write the term ½ you can say that the term is being written in terms of fraction & the digit '1' is known as the numerator while '2' is known as denominator.
How to graph fractions on a graph?
The same way student would graph numbers which are not fractions.
SAMPLE:
Graph 1/2 & 3/4 on the real number line.
<------(-2)------(-1)--------(0)------(1)-------(2)---->
Obviously, where would student put fractions 1/2 & 3/4?
The fractions would easily fit between 0 & 1, right?
The same applies to points on a graph.
SAMPLE:
Graph (2, 3/4) & (0, 1/2) on the xy-plane?

How would student graph these points?
For (2, 3/4), student travel 2 units to the right on the x-axis
& 3/4 units UP on the y-axis & plot the point there.
For (0, 1/2), student would NOT travel on the x-axis because of ZERO but student would need to travel 1/2 units UP on the y-axis and plot the point there.

square root of 48

Let us learn about square root of 48

Calculate the square root of 48. Answer: √48= 6.92820323. Factor the radicand & take the square roots of the factors.

√48 = √(16×3)
= √16√3
= 4√3
Simplify the following square root. √48 Solution: √48 = √16*3 = √16 * √3 = √4² √3 = 4√3

graph quadrants

Let us learn about graph quadrants


There are four quadrants in a graph.
The most used 1 is the first quadrants which is the top right one.
The second quadrant is the 1 on the left of it.
The third is the 1 below the second quadrant
The forth quadrant is the 1 on the graph that is below the first quadrant.
II | I
---+---
III | IV
Divide the graph into four parts & each part is called as quadrant. Traditionally, learner use the x & y axis to divide it. The portion of the graph with positive x & y coordinates is the 1st quadrant; the 2nd has positive y values & negative x values, while the 3rd quadrant has both negative x & negative y values. The last is the 4th quadrants which are below the 1st quadrant. It has positive x values & negative y values.
The point (0,0) the center of a clock, the 1st quadrant is between 3 & 12 & the 2nd between 12 & 9, the 3rd between 9 & 6 & the 4th between 12 & 3.
