Square root of a number is 2 numbers that multiply to get 4 that are the same
first find the factors
4=2 times 2
then find the doubles and write only one from each pair
√4=2
so if you had a number like 36 then
36=2 times 2 times 3 times 3
the doubles are 2 and 3 so
√36=2 times 3=6
square root of 4 can be 2 or -2
