Math Problem Statement

Simplify \((-512)^{\frac{1}{3}}\).

Solution

The expression in the image is asking to simplify (512)13(-512)^{\frac{1}{3}}, which means the cube root of 512-512.

Solution:

  1. Recall that (512)13(-512)^{\frac{1}{3}} is asking for the number that, when raised to the third power, equals 512-512.
  2. Since the base is negative and the exponent is a fraction with an odd denominator (1/31/3), the result will be negative. The cube root of a negative number is also negative.
  3. The cube root of 512512 is 88 because 83=8×8×8=5128^3 = 8 \times 8 \times 8 = 512.
  4. Therefore, (512)13=8(-512)^{\frac{1}{3}} = -8.

Final Answer:

8\boxed{-8}
