Question

What is the square root of 25/49

Answer 1

First take the square root of 25, then take the square root of 49.
It is as easy as separating the square root to apply to both terms separately instead of combined.

sqrt(25)/sqrt(49)
5/7

Answer 2

(25/49)^1/2= 5/7 where 25^1/2=5 and 49^1/2 is equal to 7
