Answer 1

Answer:

5/7

Step-by-step explanation:

(25/49)^-1/2

The exponent, (-1/2), is telling us to take the square root of (25/49).  [An exponent of (-1/2) would be the cube root]

Let's rewrite this in a more familiar format:

           $\sqrt{25/49}$

 This can also be viewed as $\sqrt{25}$/$\sqrt{49}$

     $\sqrt{25}$ = 5

     $\sqrt{49}$ = 7

Therefore, (25/49)^-1/2  = 5/7
