Math Problem Statement

Simplify \(\sqrt[3]{512}\).

Solution

The problem requires simplifying 5123\sqrt[3]{512}.

Step 1: Break 512 into prime factors

512 is a power of 2: 512=29512 = 2^9

Step 2: Apply the cube root

Using the property of exponents for cube roots: 293=29/3=23\sqrt[3]{2^9} = 2^{9/3} = 2^3

Step 3: Simplify

23=82^3 = 8

Final Answer:

5123=8\sqrt[3]{512} = 8
