Evaluate 512^(2/3)

Problem

512(2/3)

Solution

1. Rewrite the expression using the properties of rational exponents, where a(m/n)=(√(n,a))m

512(2/3)=(√(3,512))2

2. Evaluate the cube root of 512 by identifying that 8×8×8=512

√(3,512)=8

3. Substitute the result back into the expression and square the value.

8=64

Final Answer

512(2/3)=64
