solve the exponential equation. express the solution in terms of natural logarithims. Then, use a calculator to obtain a decimal point approximation for the solution.

e^x=12.3

What is the solution in terms of natural logarithims?

The solution set is ?

  • pre-calculus -

    e^x = 12.3.
    Take log of both sides:
    x*Lne = Ln12.3
    X = Ln12.3 / Lne.

    X = 12.3.
