Solve for x. Express your answer in simplest radical form if necessary.

Question

x^2 = 81

Answer 1

Taking the square root of both sides:

x = ±√81

Since 9 * 9 = 81, the square root of 81 is 9.

Therefore, x = ±9.

Answer 2

Wrong, what’s the answer?

Answer 3

Apologies for the mistake.

Taking the square root of both sides:

x = ±√(81)

x = ±9

Therefore, the solution to x^2 = 81 is x = ±9.

Answer 4

Solve for m. Express your answer in simplest radical form if necessary.

m^3 = 125

Answer 5

Taking the cube root of both sides:

m = ∛125

Since 5 * 5 * 5 = 125, the cube root of 125 is 5.

Therefore, m = 5.
