No matter what base a logarithm is, the logarithm of 1 is always zero! log_b(1)= 0 and l_n(1)= 0 Now we will do some examples showing how we combine all of these properties to expand logarithms. Example 4: Expand and simplify each logarithm. a) log_2(8x^3/y^2) = b) log (20x (x - 5)^4) = c) log_3 (9(2x - 1)^3/16x (5x^2 + 3)^7) = d) ln (e^14x (3x^4 + 5x^2 - 1)^3/(12x + 7)^5) =
