Properties of logarithms: Assuming each of the following logarithms exist: 1) ln(ab) = lna + lnb 2) ln a b = lna - lnb 3) lna b = blna (Note: These properties are true for log b x, for any base b, not just for natural logs.) Properties of exponents: 1) e a + b = e a e b 2) e a - b = e a e b 3) e ab = (e a ) b (These properties are true for all exponential functions with any base.) Since y = ln x and y = e x are inverses of each other: 1) lne m = m for all real numbers m 2)
