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/
