1. Problem Description

Solve for xx in the equation (14)x=83x2(\frac{1}{4})^x = 8^{3x-2}.

2. Solution Steps

The given equation is (14)x=83x2(\frac{1}{4})^x = 8^{3x-2}.
We can rewrite both sides of the equation using the base

2. $(\frac{1}{4})^x = (2^{-2})^x = 2^{-2x}$

83x2=(23)3x2=23(3x2)=29x68^{3x-2} = (2^3)^{3x-2} = 2^{3(3x-2)} = 2^{9x-6}
So we have 22x=29x62^{-2x} = 2^{9x-6}.
Since the bases are equal, we can equate the exponents:
2x=9x6-2x = 9x - 6
Add 2x2x to both sides:
0=11x60 = 11x - 6
Add 6 to both sides:
6=11x6 = 11x
Divide by 11:
x=611x = \frac{6}{11}

3. Final Answer

x=611x = \frac{6}{11}
