Question

Solve for 50 points
x^(2)=100

Answer 1

x = ±10 i.e. -10 or +10

Explanation:

Given that,

x² = 100

Solution:

Let's take square root to the RHS.

• x = ±√100

Solving √100 , we can obtain,

• x = ± √10*10

Further

• x = ± 10

Hence, the value of x can be -10,or +10.

Answer 2

• x = ± 10

Explanation:

• x² = 100
• √x² = √100
• x = ± 10
