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. Jan 3, 2024 at 15:30. WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2.

WebSolve e 2x = 54. e 2x = 54. ln e 2x = ln 54 . Since the base is e, use the natural logarithm. (If the base were 10, using common logarithms would be better.) ln e 2x = ln 54. 2x = ln 54. Remember that logarithms and exponential functions are inverses. When you have log b b m, the logarithm undoes the exponent, and the result is just m. So ln ...
