Answer:

Option (C)

Explanation:

Given expression is,

$4+4* \text{log}_2(x)=14$

By subtracting 4 from both the sides of the equation.

$4* \text{log}_2(x)=14-4$

Now divide the equation by 4

$\text{log}_2(x)=(10)/(4)$

$\text{log}_2(x)=2.5$

[If
$\text{log}_ab=x$ , then
b=a^(x) ]

x=(2)^(2.5)

x = 5.657

x ≈ 5.66

Therefore, Option C will be the correct option.
