Solution

Step 1 :Given the equation \(8^{2x - 10} = 9^{8x - 2}\)

Step 2 :Take the natural logarithm on both sides to get \((2x - 10) \cdot \ln(8) = (8x - 2) \cdot \ln(9)\)

Step 3 :Solve for x to get \(x = \log\left(\frac{32768}{9}\right)^{\frac{1}{\log\left(\frac{8}{6561}\right)}}\)

Step 4 :\(\boxed{x = \log\left(\frac{32768}{9}\right)^{\frac{1}{\log\left(\frac{8}{6561}\right)}}}\)
