Step-by-step solution

The given expression is (15×2)17(2×15)13 \frac{\left(15\times2\right)^{17}}{\left(2\times15\right)^{13}}. To simplify
using the rule of exponents known as the Power of a Quotient Rule, which states

When you divide like bases you subtract the exponents:

aman=amn \frac{a^m}{a^n} = a^{m-n} .

First, notice that both the numerator and denominator have the base 15×2 15 \times 2 . Therefore, we can simplify by subtracting the exponents in the numerator and the denominator:

  • Numerator's exponent: 17
  • Denominator's exponent: 13

We apply the quotient rule:

(15×2)1713 (15 \times 2)^{17-13} .

As a result, the simplified expression is (15×2)4 (15 \times 2)^4 .
Therefore, the correct answer which represents the expression using the Power of a Quotient Rule is

(15×2)1713 \left(15\times2\right)^{17-13}

because it encapsulates the subtraction of exponents without computing the final exponent 4.

This allows you to keep the expression in its most simplistic exponential form.

Final Answer

(15×2)1713 \left(15\times2\right)^{17-13}
