Beyond the Answer
To solve the equation \( \left(\frac{\pi}{3}\right)^{x+2} = \left(\frac{3}{5}\right)^{x} \), start by taking the natural logarithm of both sides: \[ \ln\left(\left(\frac{\pi}{3}\right)^{x+2}\right) = \ln\left(\left(\frac{3}{5}\right)^{x}\right) \] Applying the power rule for logarithms, this becomes: \[ (x+2)\ln\left(\frac{\pi}{3}\right) = x\ln\left(\frac{3}{5}\right) \] Next, distribute and rearrange to isolate \(x\): \[ x \ln\left(\frac{\pi}{3}\right) + 2 \ln\left(\frac{\pi}{3}\right) = x \ln\left(\frac{3}{5}\right) \] Combining the terms gives: \[ x \left(\ln\left(\frac{\pi}{3}\right) - \ln\left(\frac{3}{5}\right)\right) = -2 \ln\left(\frac{\pi}{3}\right) \] Finally, solve for \(x\): \[ x = \frac{-2 \ln\left(\frac{\pi}{3}\right)}{\ln\left(\frac{\pi}{3}\right) - \ln\left(\frac{3}{5}\right)} \] Now you can plug this into a calculator to find the numerical value of \(x\). Happy calculating!
