Step-by-step solution

To solve the problem, we will follow these steps:

  • Step 1: Identify the expression and apply the rule for negative exponents.
  • Step 2: Take the reciprocal of the given fraction 1017 \frac{10}{17} .
  • Step 3: Raise the reciprocal to the positive power of 5.

Now, let's work through each step:
Step 1: We start with the problem expression (1017)5 \left(\frac{10}{17}\right)^{-5} . According to the laws of exponents, a negative exponent means the reciprocal of the base should be raised to the positive of that exponent.
Step 2: Take the reciprocal of 1017 \frac{10}{17} , which is 1710 \frac{17}{10} .
Step 3: Raise the reciprocal 1710 \frac{17}{10} to the power of 5, resulting in (1710)5 \left(\frac{17}{10}\right)^5 .

Therefore, the equivalent expression is (1710)5 \left(\frac{17}{10}\right)^5 .
