WebNov 24, 2024 · I am having trouble with the following problem, which is about solving exponential equations using logarithms with base 10: Initially, I thought I'd take the log of $2^x-1$ and $4^{2x+1}$ separately, and then multiply them. But that didn't work, because there's no rule for multiplying logs to combine them. WebIn the video we define a logarithm. We also discuss the laws of logarithms and how logarithms relate to exponents. We solve exponential equations using the logarithms and vice versa. 5. Logarithmic Functions In this video, we discuss how the logarithmic function relates to the exponential function. We extensively use the reflection in the line y=x.

Solving exponents using logarithms

WebJul 9, 2024 · Take the log of both sides. You can take any log you want, but remember that you actually need to solve the equation with this log, so you should use common or natural logs only. Using the common log on both sides gives you log 4 3x –1 = log 11. Use the power rule to drop down the exponent. This step gives you (3 x – 1)log 4 = log 11. WebTo show why this is true, we offer a proof. Since the logarithm and exponential undo each other, 10logA = A 10 log A = A. So Ar = (10logA)r A r = ( 10 log A) r. Utilizing the exponential rule that states (xa)b = xab ( x a) b = x a b, Ar = (10logA)r …
