Question

What is the square root of 4

Answer 1

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

Answer 2

the answer is 2 because 2 × 2 = 4 or you can do 4 ÷ 2 to check your work
