Problem
Select the expression that is equivalent to \( \frac{1}{(2 x-2)^{-\frac{1}{2}}} \) \( \sqrt{2 x-2} \) \( \frac{1}{\sqrt{(2 x-2)^{2}}} \) Submit Answer \( \sqrt{(2 x-2)^{2}} \) \( \frac{1}{\sqrt{2 x-2}} \)
Solution
Step 1 ：\( \frac{1}{(2 x-2)^{-\frac{1}{2}}}=(2 x-2)^{\frac{1}{2}} \)
Step 2 ：\( (2 x-2)^{\frac{1}{2}}=\sqrt{2 x-2} \)
Step 3 ：\( \sqrt{2 x-2} \)
