Practicing problems is the best way to learn and online resources now give students plenty of practice material to work on. Find 6th grade math problems with answers online and use them to learn and practice math.

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

Step 1:

Factors of 125

125 = 5 * 5 * 5 = 5^{3}

Step 2:

=> $(x - 1)^\frac{3}{2}$ = 5^{3}

On squaring both side, we have

=> $(x - 1)^{\frac{3}{2} * 2} $ = (5^{3} )^{2 }

=> $(x - 1)^3$ = 5^{6} [ (x^{m} )^{n} = x^{mn} ]^{ }

Step 3:

Taking cube root of both sides

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

=> x - 1 = 5^{2}

=> x - 1 = 25

=> x = 25 + 1

=> x = 26.**answer**

Step 1:

Factors of 125

125 = 5 * 5 * 5 = 5

Step 2:

=> $(x - 1)^\frac{3}{2}$ = 5

On squaring both side, we have

=> $(x - 1)^{\frac{3}{2} * 2} $ = (5

=> $(x - 1)^3$ = 5

Step 3:

Taking cube root of both sides

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

=> x - 1 = 5

=> x - 1 = 25

=> x = 25 + 1

=> x = 26.

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**

Total number of the questions in the exam = 120

He got 75 % of the total.

The number of question Brovo got right

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

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

=> 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.

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 = $\pi$ r^{2} , 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.

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 = $\pi$ r

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

= 3.14 * 36

Step 2:

Area of circle = 3.14 * 36

= 113. 04

or 113.0(approx)

=> Area of the circle = 113 square inches.
