PLS HELP!!<br>what is the value of x?<br>log2(x+7) = 2

Sedbober [7]

Answer: Choice A) -3

Work Shown:

$\log_{2}(x+7) = 2\\\\x+7 = 2^2\\\\x+7 = 4\\\\x = 4-7\\\\x = -3\\\\$

Which leads us to choice A. In the second step, I used the rule that $\log_b(y) = x$ is equivalent to $y = b^x$ . For each equation, the b is the base. Note how logs undo exponents and vice versa.
