Answer 1

Answer:

n=9

S-B-S explanation: /Strikethrough/ - this means you can cut these parts out because they are not needed.

/log/(n+2) = /log/(n^2-70)

/n+2/ = n^2-70

/-n-2/____-n-2

------------------------------

= (0=n^2--n--72)

(n-9) =0 ______ (n+8) =0

n-9= 0 _______ n+8= 0

+9= +9 ________ -8= -8

-------------________-------------

__n=9___________ /n=-8/
