Question

Solve for x to four significant digits

7^2x-1=316

Answer 1

First, you would convert the exponential equation into logarithmic form. This would be log(7)316 = 2x - 1. Then, you would do (log(316))/(log(7)). Finally, you would add 1 and divide by 2. This would give you a final (4 sig figs) answer of x = 1.979.

Hope this helps!
