Math Problem Statement

log4 2=3x-8 (break down simple solution)

Solution

To solve the equation log42=3x8\log_4 2 = 3x - 8, we'll break it down into simple steps:

Step 1: Understand the logarithmic expression

The equation log42\log_4 2 represents the logarithm of 2 with base 4. This asks, "To what power must 4 be raised to get 2?"

Step 2: Solve the logarithm

Since 412=24^{\frac{1}{2}} = 2, we know that: log42=12\log_4 2 = \frac{1}{2} So the equation becomes: 12=3x8\frac{1}{2} = 3x - 8

Step 3: Solve for xx

Now, solve the linear equation 12=3x8\frac{1}{2} = 3x - 8.

  1. Add 8 to both sides to isolate the term with xx: 12+8=3x\frac{1}{2} + 8 = 3x 12+162=3x\frac{1}{2} + \frac{16}{2} = 3x 172=3x\frac{17}{2} = 3x

  2. Divide both sides by 3 to solve for xx: x=1723x = \frac{\frac{17}{2}}{3} x=176x = \frac{17}{6}

Final Answer

The solution is: x=1762.83x = \frac{17}{6} \approx 2.83
