Math Problem Statement

Solve log_2(x - 12) = 4.

Solution

The problem presented is:

log2(x12)=4\log_2(x - 12) = 4

To solve for xx, follow these steps:

Step 1: Rewrite the logarithmic equation in exponential form

Since log2(x12)=4\log_2(x - 12) = 4, we can rewrite it as: x12=24x - 12 = 2^4

Step 2: Calculate 242^4

24=162^4 = 16 So, x12=16x - 12 = 16

Step 3: Solve for xx

Add 12 to both sides: x=16+12x = 16 + 12 x=28x = 28

Answer:

x=28x = 28

Tip

When solving logarithmic equations, remember that logb(a)=c\log_b(a) = c translates to a=bca = b^c. This is often the key step in finding solutions.
