Question
Find the exact solution of the exponential equation in terms of logarithms.
Given equation:
Solution
Sure, here are the steps to solve the equation e^(7 - 8x) = 18:
Step 1: Take the natural logarithm (ln) on both sides of the equation to get rid of the base e on the left side. This gives us:
7 - 8x = ln(18)
Step 2: Isolate the term with x by subtracting 7 from both sides:
-8x = ln(18) - 7
Step 3: Finally, solve for x by dividing both sides by -8:
x = (ln(18) - 7) / -8
So, the exact solution of the exponential equation in terms of logarithms is x = (ln(18) - 7) / -8.
