Solve for x logarithm
WebDec 29, 2024 · Here is an example of how to solve a logarithm. Consider 2log2x+log24−3= 1 2 log 2 x + log 2 4 − 3 = 1. First, add 7 to both sides to find that 2log2x+log24 =4 2 log 2 x + log 2 4 = 4. Then ... WebExample 5. Solve the logarithmic equation log 2 (x +1) – log 2 (x – 4) = 3. Solution. First simplify the logarithms by applying the quotient rule as shown below. log 2 (x +1) – log 2 (x – 4) = 3 ⇒ log 2 [ (x + 1)/ (x – 4)] = 3. Now, rewrite the equation in exponential form.

Web9 years ago. 1st Isolate the base with the exponent by dividing both sides by 5 and you get: 10^x-31=16.32. 2nd log both sides. log 10 of 10^x-31=log 10 of 16.32. The log 10 and 10 cancel out, your left with: x-31=log 10 of 16.32. 3rd add 31 to both sides to isolate x. x=log 10 of 16.32 +31. 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 ≈ …
