Step-by-step solution

To solve this problem, we'll follow these steps:

  • Simplify the expression inside the square root using exponent rules.
  • Evaluate the square root of the simplified expression.

Let's work through the solution step-by-step:

First, simplify the expression inside the square root. We have:

x20x24=x2024=x4 \frac{x^{20}}{x^{24}} = x^{20-24} = x^{-4}

Next, apply the square root to the simplified expression:

x4=(x4)1/2=x4×12=x2 \sqrt{x^{-4}} = \left(x^{-4}\right)^{1/2} = x^{-4 \times \frac{1}{2}} = x^{-2}

This can be written as:

x2=1x2 x^{-2} = \frac{1}{x^2}

Therefore, the solution to the problem is 1x2\frac{1}{x^2}.
