How to add logarithms with different bases
Nettet3 Answers Sorted by: 3 You can do a bit more simplification. The important properties of the log function are, for any base a > 0, log a ( b c) = log a b + log a c, so, for example, log 2 6 = log 2 2 + log 2 3 log a ( b / c) = log a b − log a c log a b n = n log a b log a b = 1 / log b a ( log a b) ( log b c) = log a c log a a = 1 NettetHow to solve exponential equations with different bases? When it’s not convenient to rewrite each side of an exponential equation so that it has the same base, you do the following: Take the log (or ln) of both sides Apply power property Solve for the variable Example: Solve for x. a) 6 x = 42 b) 7 x = 20 c) 8 2x - 5 = 5 x + 1 d) 3 x = 5 x - 1
