Find the solution(s) to each equation x^(2) = 9 √(x) = 3 √(x) = - 3 ​

Question

Find the solution(s) to each equation


`x^(2) = 9`

`√(x) = 3`

`√(x) = - 3`
​

Answer 1

Explanation:

`x^(2) = 9\\\sqrt{x^(2) } = √(9) \\x = 3\\\\√(x) =3\\(√(x))^(2) = 3^(2) \\x=9\\\\√(x) =-3\\(√(x) )^(2)=-3^(2) \\x=9`
