Evaluate (8/27)^(2/3)

Problem

(8/27)(2/3)

Solution

1. Apply the power of a quotient rule to distribute the exponent to both the numerator and the denominator.

(8/27)(2/3)=(8(2/3))/(27(2/3))

2. Rewrite the rational exponent as a radical using the property a(m/n)=(√(n,a))m

(8(2/3))/(27(2/3))=((√(3,8))2)/((√(3,27))2)

3. Evaluate the cube roots in the numerator and denominator.

√(3,8)=2

√(3,27)=3

4. Substitute the roots back into the expression and square the results.

2/3=4/9

Final Answer

(8/27)(2/3)=4/9
