Its 2. 2 times 2 is 4. when ur looking for the square root u are looking for two numbers that multiplied gives u the number like if ur looking for the square root of 16 u are looking for 2 numbers that multiplied give 16. the answer is 4 because 4 times 4 is 16. easy... :)

The square root of 4 is 2.
2x2=4

I support jd23.

the reason for square root of 4 equals +2,-2 is

2x2 = 4
&
(-2)x(-2) = 4

so square root of any number is a positive and a negative quantity

4=(+2)^2 and also (-2)^2
therefore 4^1/2 =+2 and-2

2, square root is a number times itself equals a number. E.g. 6×6=36, square root of 36 is 6.

if 4 is the number...16 is the square....the square root is 2.000
