Solve for x. Express your answer in simplest radical form if necessary.
x^2 = 81
Taking the square root of both sides:
x = ±√81
Since 9 * 9 = 81, the square root of 81 is 9.
Therefore, x = ±9.
Wrong, what’s the answer?
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.
Solve for m. Express your answer in simplest radical form if necessary.
m^3 = 125
Taking the cube root of both sides:
m = ∛125
Since 5 * 5 * 5 = 125, the cube root of 125 is 5.
Therefore, m = 5.
