Here we are going to see some practice questions on solving radical equations with radicals on both sides.

In order to remove radical signs, we have to take squares on both sides.

## Solving radical equations with radicals on both sides worksheet - Questions

(1)  Solve the following equation.

52  =  x

(2)  Solve the following equation.

3√7  =  √-y

(3)  Solve the following equation.

√(3x + 12)  =  3√3

(4)  Solve the following equation.

√(x - 5)  =  2√6

(5)  Solve the following equation.

√(3x - 4)  =  √6

## Solving radical equations with radicals on both sides worksheet - Solution

Question 1 :

Solve the following equation.

52  =  x

Solution :

52  =  x

By taking squares on both sides, we get

(52)2  =  x2

5222  =  x2

25(2)  =  x

x  =  50

Question 2 :

Solve the following equation.

3√7  =  √-y

Solution :

3√7  =  √-y

By taking squares on both sides, we get

(3√7)2  = ( √-y)2

32√72  =  y

9(7)  =  y

y  =  63

Question 3 :

Solve the following equation.

√(3x + 12)  =  3√3

Solution :

√(3x + 12)  =  3√3

By taking squares on both sides, we get

(√3x + 12)2  = (3√3)2

3x + 12  =  32√32

3x + 12  =  9 (3)

3x + 12  =  27

Subtract 12 on both sides, we get

3x + 12 - 12  =  27 - 12

3x  =  15

Divide by 3 on both sides

3x / 3  =  15/3

x  =  5

Question 4 :

Solve the following equation.

√(x - 5)  =  2√6

Solution :

√(x - 5)  =  2√6

By taking squares on both sides, we get

(√(x - 5))2  = (2√6)2

x - 5  =  22√62

x - 5  =  4 (6)

x - 5  =  24

x - 5 + 5  =  24  + 5

x  =  29

Question 5 :

Solve the following equation.

√(3x - 4)  =  √6

Solution :

√(3x - 4)  =  √6

By taking squares on both sides, we get

(√(3x - 4))2  = (√6)2

3x - 4  =  √62

3x - 4  =  6

3x - 4 + 4  =  6 + 4

3x  =  10

Divide by 3 on both sides

3x/3  =  10/3

x  =  10/3
