Solution

To solve the equation 32x=13 3^2x = 13 , we need to isolate x x . Here are the steps:

  1. Rewrite the equation: 32x=13 3^{2x} = 13

  2. Take the natural logarithm (ln) of both sides: ln(32x)=ln(13) \ln(3^{2x}) = \ln(13)

  3. Use the logarithm power rule ln(ab)=bln(a) \ln(a^b) = b \ln(a) : 2xln(3)=ln(13) 2x \ln(3) = \ln(13)

  4. Solve for x x : x=ln(13)2ln(3) x = \frac{\ln(13)}{2 \ln(3)}

  5. Calculate the value: x2.56492×1.0986 x \approx \frac{2.5649}{2 \times 1.0986} x2.56492.1972 x \approx \frac{2.5649}{2.1972} x1.167 x \approx 1.167

Since none of the provided options (A. 1, B. -1, C. -12, D. 12) exactly match the calculated value, it appears there might be a mistake in the problem statement or the provided options. However, based on the closest approximation, the answer would be closest to:

A. 1
