Answer:
Option C. is the correct option.
Step-by-step explanation:
The given expression is [tex]log_{2}(x+11)=4[/tex]
We further solve this
[tex](x+11)=2^{4}=16[/tex]
[tex]x = 16-11=5[/tex]
Now we evaluate the options
A). [tex]log_{5}16\neq 2[/tex]
But the expression is given as [tex]log_{2}(x+11)=4[/tex]
Wrong expression so not correct.
B). [tex]log_{5}16\neq 4[/tex]
Wrong expression again so not correct
C). By putting x = 5 in the expression
[tex]log_{2}(x+11)=4[/tex]
[tex]log_{2}(5+11)=log_{2}(16)=log_{2}(2^{4})=4[/tex]
Therefore this option is the correct option.
D). By putting x = 5 in the expression
[tex]log_{4}(5+11)=log_{4}(16)=log_{4}(4^{2})=2[/tex]
But the expression is [tex]log_{2}(x+11)=4[/tex]
So this option is also not correct.
