Extract Square Root Of (M-4)\Xb2-81=0

Extract square root of (m-4)²-81=0

Hello!

Answer:

$\boxed{m=13, m=-5}\checkmark$

Step-by-step explanation:

For (yx²)= c(a) for the solutions of c(x)=√c(a)-√c(a)

First, you add by 81 both sides.

$(m-4)^2-81+81=0+81$

Then, you add numbers from left to right.

$(m-4)^2=81$

$\boxed{m=13, m=-5}$ , which is our final answer.

Hope this helps you!

Have a nice day! :)
