Math Problem Statement

Bentuk sederhana dari (2m^5n^{-5}) / (32m^7n^{-1}) adalah?

Solution

The problem in the image asks for the simplified form of the expression:

(2m5n5)(32m7n1)\frac{(2m^5n^{-5})}{(32m^7n^{-1})}

Step-by-step solution:

  1. Simplify the coefficients: 232=116\frac{2}{32} = \frac{1}{16} So the expression becomes: m5n5m7n1116\frac{m^5n^{-5}}{m^7n^{-1}} \cdot \frac{1}{16}

  2. Simplify the powers of mm: Using the quotient rule of exponents aman=amn\frac{a^m}{a^n} = a^{m-n}: m5m7=m57=m2\frac{m^5}{m^7} = m^{5-7} = m^{-2}

  3. Simplify the powers of nn: Similarly, for nn: n5n1=n5(1)=n5+1=n4\frac{n^{-5}}{n^{-1}} = n^{-5 - (-1)} = n^{-5 + 1} = n^{-4}

  4. Combine the results: So far, we have: 116m2n4=m2n416\frac{1}{16} \cdot m^{-2} \cdot n^{-4} = \frac{m^{-2}n^{-4}}{16}

    This can be written as: 116m2n4\frac{1}{16m^2n^4}

The correct answer is 116m2n4\boxed{\frac{1}{16m^2n^4}}, but the choices suggest we need to match a given format. Since this doesn't directly appear, the most likely simplification based on the image choices would be 116m2n4\boxed{\frac{1}{16m^2n^4}}.
