Answer:
[tex]\boxed{\underline{\tt B.\:x=-1}}[/tex]
Step-by-step explanation:
[tex]\tt 8=2^{(x+4)}[/tex]
(First, convert both sides to the same base):-
[tex]\tt 2^3=2^{x+4}[/tex]
(Now, cancel the base of 2 on both sides):-
[tex]\tt 3=x+4[/tex]
(Subtract 4 from both sides):-
[tex]x+4-4=3-4[/tex]
[tex]\tt x=-1[/tex]
