Question

Ayee someone help pleasee

Answer 1

Both are solutions of x.

Explanation:

`x^(2) =49`

For
`x^(2) =f(a)` the solutions are
`x=√(f(a)) ,-√(f(a))`

`x=√(49) ,x=-√(49)`

`√(49)`

Factor the number:
`49=7^(2)`

Apply radical rule:
`\sqrt[n]{x^n} =a`

`√(7^2) =7`

=7

`-√(49)`

Factor the number:
`49=-7^2`

Apply radical rule:
`\sqrt[n]{x^n} =a`

`-√(7^2)=7`

`=-7`
