Experts are tested by Chegg as specialists in their subject area. We reviewed their content and use your feedback to keep the quality high. WebFrom the change of base theorem, log base a of b = (ln b)/ (ln a). For example, you can calculate log base 3 of 5 by calculating (ln 5)/ (ln 3) which should give approximately 1.465. (Note that if your calculator also has a log key, another way to calculate log base 3 of 5 is to …

Webthe answer is -2, 4 is 2^2 and 25=5^2 so 4/25 is the inverse of (5/2)^2 so its (5/2)^-2. to solve this you either have to just see how -2 would make everything line up, or plug it into a calculator with logs and then when the calculator says -2 justify why its exactly -2. WebApr 17, 2024 · Explanation: Using properties of logarithms we can rewrite the left hand side. log(a) +log(b) = log(ab) log9((x − 5)(x + 3)) = 1. Now rewrite both sides in terms of the … inclanbhr

WebTo solve for y, first take the log of both sides: log 5 = log 3 y. By the identity log x y = y · log x we get: log 5 = y ⋅ log 3. Dividing both sides by log 3: y = log 5 log 3. Using a calculator we can find that log 5 ≈ 0.69897 and log 3 ≈ … WebMar 28, 2024 · Step 1: Isolate the exponential expression. 52x − 1 + 2 = 9 52x − 1 = 7. Step 2: Take the logarithm of both sides. In this case, we will take the common logarithm of both sides so that we can approximate our result on a calculator. log52x − 1 = log7. Step 3: Apply the power rule for logarithms and then solve.
