Math Problem Statement

Tuliskan dalam bentuk pangkat positif: (5^{-2})^3

Solution

The problem asks to rewrite the expression (52)3(5^{-2})^3 using positive exponents. Let's solve this step by step.

Step 1: Apply the power of a power rule

The power of a power rule states that (am)n=amn(a^m)^n = a^{m \cdot n}.

Here, a=5a = 5, m=2m = -2, and n=3n = 3.

(52)3=52×3=56(5^{-2})^3 = 5^{-2 \times 3} = 5^{-6}

Step 2: Convert to a positive exponent

To convert 565^{-6} to an expression with a positive exponent, use the reciprocal rule: an=1ana^{-n} = \frac{1}{a^n}.

56=1565^{-6} = \frac{1}{5^6}

Final Answer:

The expression (52)3(5^{-2})^3 in positive exponent form is 156\frac{1}{5^6}.
