Question 895950
# 1


Since 4^2 = 4*4 = 16


this means sqrt(16) = 4


The square root undoes what squaring does. It's like how division undoes multiplication



Note: sqrt stands for "square root"


-------------------------------------------


5^2 = 25


So sqrt(25) = 5


===================================================================


# 2


5^3 = 5*5*5 = 125 is correct


So is 20^2 = 20*20 = 400


Nice job on this problem.
