WebJan 3, 2024 · 1. The identity that is applicable is log 10 b log 10 a = log a b. However, depending on the table you have, you are probably better off keeping it this way, or even splitting the logs further as log 10 b = ln b ln 10 and log 10 a = ln a ln 10, if the table is of natural logarithms. – user517969.

WebMay 23, 2014 · May 23, 2014 at 15:38. 1. log and exponentiation are inverse functions. When you have something like log (x+1)+log (4-x)=log (100) you can solve this analytically by usage of the log laws. log (x+1) + log (x-4) = log ( (x+1)* (x-4)) then log ( (x+1)* (x-4)) = log (100) => (x+1)* (x-4) = 100 which is just a quadratic which is straightforward to ... WebFeb 14, 2016 · 59. To evaluate log8128, let log8128 = x Then by definition of the logarithm, 8x = 128 Since 8 = 23 and 128 = 27, we obtain (23)x = 27 23x = 27 If two exponentials with the same base are equal, then their exponents must be equal. Hence, 3x = 7 x = 7 3. Check: If x = 7 3, then 8x = 87 3 = (81 3)7 = 27 = 128.
