Question

Ayee someone help pleasee

Answer 1

Answer:

Both are solutions of x.

Step-by-step explanation:

$x^{2} =49$

For $x^{2} =f(a)$ the solutions  are $x=\sqrt{f(a)} ,-\sqrt{f(a)}$

$x=\sqrt{49} ,x=-\sqrt{49}$

$\sqrt{49}$

Factor  the number: $49=7^{2}$

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

$\sqrt{7^2} =7$

=7

$-\sqrt{49}$

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

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

$-\sqrt{7^2}=7$

$=-7$
