Question

Solve the exponential equation. Express the solution set in terms of natural Logarithms.

3^x+8=5

Answer 1

3^x + 8 or 3^(x+8) ?

Answer 2

x+8 is the exponent of 3

Answer 3

oh ok, it is 3^(x+8) = 5

put ln on both sides, get
ln 3^(x+8) = ln 5
(x+8) ln 3 = ln 5
x+8 = ln5/ln3
x = ln5/ln3 - 8

Answer 4

Thank you
