Solving log without a calculator
WebSolving Logarithmic Equations Here we will solve some logarithmic equations. There are a couple of ways to solve a logarithmic equation. One method is to get all logs to the left side of the equal sign and condense the problem so there is only one log. The next step would be to write the problem in exponential form and solve.

WebSometimes a logarithm is written without a base, like this: log (100) This usually means that the base is really 10. It is called a "common logarithm". Engineers love to use it. On a calculator it is the "log" button. It is how many times we need to use 10 in a multiplication, to get our desired number. Example: log (1000) = log10(1000) = 3.

WebMar 10, 2024 · 3. Apply the quotient rule. If there are two logarithms in the equation and one must be subtracted by the other, you can and should use the quotient rule to combine the two logarithms into one. Example: log 3 (x + 6) - log 3 (x - 2) = 2. log 3 [ (x + 6) / (x - 2)] = 2. 4. Rewrite the equation in exponential form. WebIf they are natural logs, I know $\log 2 \approx 0.693$ so would say $\log 1.66 = \log 2 + \log (1-0.16) \approx 0.693 -0.16 + \frac {0.16^2}2-\frac {0.16^3}3$ where the next term is …

WebKnowing the squares, cubes, and roots of numbers allows us to evaluate many logarithms mentally. For example, consider log28 l o g 2 8. We ask, “To what exponent must 2 be raised in order to get 8?”. Because we already know 23 =8 2 3 = 8, it follows that log28= 3 l o g 2 8 = 3.
