${(\frac{1}{2} \cdot {(x - 1)}^{- \frac{1}{2}})}^{2}$

Step 1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

${(\frac{1}{2} \cdot \frac{1}{{(x - 1)}^{\frac{1}{2}}})}^{2}$

Step 2

Combine.

${(\frac{1 \cdot 1}{2 {(x - 1)}^{\frac{1}{2}}})}^{2}$

Step 3

Multiply $1$ by $1$ .

${(\frac{1}{2 {(x - 1)}^{\frac{1}{2}}})}^{2}$

Step 4

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.
