Math Problem Statement
Simplify \((-512)^{\frac{1}{3}}\).
Solution
The expression in the image is asking to simplify , which means the cube root of .
Solution:
- Recall that is asking for the number that, when raised to the third power, equals .
- Since the base is negative and the exponent is a fraction with an odd denominator (), the result will be negative. The cube root of a negative number is also negative.
- The cube root of is because .
- Therefore, .
