Help i have to submit this in ten mins btw its grade 10

Step-by-step explanation:

( (625)^(1/2)  )^1/2

The safest and best way to do this is one set of brackets at a time using 1 exponent at a time.

The next best way is to combine the exponents and find the 1/4 root once. Both answers should be the same.

(625)^1/2 = sqrt(625) = 25

(25)^1/2 = 5

((625)^(1/2))^1/2 = 625^1/4 = 5

i believe the answer is c.
