Question

1

Answer 1

well, start by squaring both sides.

Answer 2

solve for x =-1

Answer 3

so 5=(2x+6) then if I square it? sorry, I'm really bad at these problems.

Answer 4

so 125 = 5^(2x+6)
or 5^3 = 5^(2x+6)

Answer 5

sorry 25^2 =/= 125, but rather 625

Answer 6

so it should say 625 = 5^(2x+6)
or 5^4 = 5^(2x+6)

Answer 7

Ahhhh, the other way around whoops. So then 625=5^(2x+6) do you then divide by 5?
