Question

Solve the following equation exactly. Use an inverse function when appropriate.
√x³ - 100 = 5

Answer 1

Starting with the given equation:

√x³ - 100 = 5

Adding 100 to both sides:

√x³ = 105

Squaring both sides:

x³ = 11025

Taking the cube root of both sides:

x = 15

Therefore, the exact solution to the given equation is x = 15.

Note that no inverse functions were needed to solve this equation
