Question

The equation x2 = 25 has two solutions. This is because both 5 • 5 = 25, and also -5 •

-5 = 25. So, 5 is a solution, and also -5 is a solution. But! The equation x3 = 125 only
has one solution, which is 5. This is because 5 • 5 • 5 = 125, and there are no other numbers you can cube to make 125. (Think about why -5 is not a solution!)
Find all the solutions to each equation.

x^3 = 8

Answer 1

2

Explanation:

The only answer that it can be is 2 because 2 * 2 * 2 = 8. But it cannot be -2 because -2 * -2 * -2 = -8. When you have a even exponent, there is often 2 solutions.
