How do I solve this logarithm equation with different bases?

WebApr 10, 2024 · Sometimes the terms of an exponential equation cannot be rewritten with a common base. In these cases, we solve by taking the logarithm of each side. Recall, since log(a) = log(b) is equivalent to a = b, we may apply logarithms with the same base on both sides of an exponential equation. Web1 = log10 (because 10^1 = 10, and that can be written as log base 10 of 10, or log10), so the equation is: log (63x^2)=log (10) Now, if you now that the logarithm base 10 of something equals the logarithm base 10 of something else, you know that that something is equal to that something else: 63x^2 = 10 now you can easily solve for x: x^2 = 10/63 WebThe equations with logarithms on both sides of the equal to sign take log M = log N, which is the same as M = N.

WebSince they have a common base, add the exponents using the Product Rule. It’s obvious that by having a single and the same base on both sides, we can now set each power equal to each other. Solve the linear equation by adding both sides by 6 6 to get x = 9 x = 9. And so the solution is x = 9 x = 9.

WebOct 18, 2024 · It’s easier for us to evaluate logs of base 10 or base e, because calculators usually have log and ln buttons for these. When the base is anything other than 10 or e, we can use the change of base formula. WebThe exact solution is x=\log_2 (48) x = log2(48). Since 48 48 is not a rational power of 2 2, we must use the change of base rule and our calculators to evaluate the logarithm. This is shown below.
