Step-by-step solution

To solve this mathematical expression, follow these steps:

  • Step 1: Use the Quotient Property of Exponents

    Simplify the expression inside the square root using the rule:
    x8x10=x810=x2 \frac{x^8}{x^{10}} = x^{8-10} = x^{-2} .

  • Step 2: Apply the Square Root Property

    Now, apply the square root:
    x2=(x2)1/2=x212=x1 \sqrt{x^{-2}} = (x^{-2})^{1/2} = x^{-2 \cdot \frac{1}{2}} = x^{-1} .

  • Step 3: Express in Simpler Form

    The expression x1 x^{-1} can be written as 1x\frac{1}{x}.

Therefore, the final simplified form of the expression is 1x \frac{1}{x} .
