Hope I helped.

Answer 2

B - 25

C. 25

Explanation:

What are the solutions to the equation x² = 625?

The expression is

x² = 625

The expression want us to find the value of x.

x² = 625

since x is in square, to cancel the square on x we square root both sides.

Square rooting both sides

√x² = √625

x = √625

x = 25

The value of x is 25

The answer can also be -25 , since the square of -25 is also equals to 625.

-25 × -25 = 625
