metal fan how do i find the square root to an equation (a^2=324)

Answer 1

find the sqyare root of 324 and that's your answer

Answer 2

a = square root of 324

Answer 3

actually that is not exactly correct.

Answer 4

sqrt(324) = 18

18^2 = 324

a = 18

Answer 5

when you say "square root of 324" you are talking about the positive value of the root. (that is how we normally presume in math).

when finding roots though, you have the +- sign

Answer 6

why? because (-18)^2 and (18)^2 are both 324

Answer 7

unless you have other conditions, by which you would exclude the negative solution

Answer 8

thank you i got it now

Answer 9
