Answer:
it would be √c
Explanation:
when you have fractional exponets, the denominator becomes the radical that you want to find so in this case since its 2 it would be he nomal √ (remeber that when you have a √ with no numbers. it automatically indciates that there is a two) , the numerator of the fraction is the exponent of the number that is inside the radical so in reality it would be √c^1 but we don't write the exponent 1 so it would be √c
hipe this helps :)
