Solved Examples

Question 1: Solve for x, $(x - 1)^\frac{3}{2}$ = 125

Solution:
Given $(x - 1)^\frac{3}{2}$ = 125

Step 1:

Factors of 125

125 = 5 * 5 * 5 = 53

Step 2:


=>  $(x - 1)^\frac{3}{2}$ = 53

On squaring both side, we have

=> $(x - 1)^{\frac{3}{2} * 2} $ = (53 )

=> $(x - 1)^3$ = 56                     [ (xm )n = xmn ] 

Step 3:

Taking cube root of both sides

=> $((x - 1)^3)^\frac{1}{3}$ = $(5^6)^\frac{1}{3}  $

=> x - 1 = 52

=> x - 1 = 25

=> x = 25 + 1

=> x = 26. answer
 

Question 2: There were 120 questions on the math exam. Bravo got 65% of them right. How many questions did he get right.

Solution:
Let number of questions Bravo got right = x

Step 1:
Total number of the questions in the exam = 120
He got 75 % of the total.

The number of question Brovo got right

=> $\frac{Number\ of   question \ Brovo \ got \ right}{Total \ number \ of \ question} = \frac{65}{100}$

=> $\frac{x}{120} = \frac{65}{100}$

Step 2:
Solve for x,

$\frac{x}{120} = \frac{65}{100}$

=> 100 * x = 65 * 120

=> x = $\frac{65 * 120}{100}$

=> x = $\frac{5 * 13 * 2 * 2 * 2 * 3 * 5}{2 * 2 * 5 * 5}$

=> x = 2 * 3 * 13

=> x = 78

Hence Brovo got 78 questions right. answer
 

Question 3: Find the area of a circle with a diameter 12 inches and round the answer to the nearest tenth of an inch.(use $\pi$ = 3.14).

Solution:
Given:
Diameter of the circle = 12 in.
then radius of the circle = $\frac{12}{2}$ = 6 in

[ Radius = $\frac{Diameter}{2}$ ]

Step 1:

[ Area of circle = $\pi$ r2 , r = radius ]

=> Area of circle = $\pi$ (6)2

= 3.14 * 36

Step 2:


Area of circle = 3.14 * 36

= 113. 04

or 113.0(approx)

=> Area of the circle = 113 square inches.
