Solve for x: 9^x-3^x-8=0

Answers

To solve for x, we will use the natural log (ln) function and the change of base rule. Change of Base Rule: ln (b^x) = x ln (b) Applying this to the equation, we get: ln (9^x) - ln (3^x) - ln (8) = 0 ln (9^x) - ln (3^x) = ln (8) x ln (9) - x ln (3) = ln (8) x (ln (9) - ln (3)) = ln (8) x = ln (8) / (ln (9) - ln (3)) x = 1.36591 Therefore, x = 1.36591.
