Answer 3

um, use a calculator, that's all i can tell you, i know what the square root of 16 is! it's 4 ha! i'm smart

Answer 4

See if you can understand this.

sqr (X^2) = X^(2/2) = X

If this went way over your head just forget I even wrote this.

Answer 5

you can now used a scientific calculator but if you want to solved it manually try this one....

example: √10

solution: √10

              = 10 raise 1/2

              =  10/2

              =   2
