WebExplanation: The easiest and fastest way to calculate the value of log 5 is with the help of a logarithmic table. According to the logarithmic table, value of log 5 = 0.6990. Also, with the help of the logarithmic formula log (A/B) = log A - log B we can calculate value of log 5. As, log 5 = log (10/2) WebApr 16, 2016 · you can follow this way. log5 = log( 10 2) = 1 − log2 = 1 − 0.3 = 0.7. If you want a general way to find logarithms without using calculators or tables, you could use this formula: (1 2)ln∣∣ ∣ 1 + x 1 − x ∣∣ ∣ = f (x) = x + x3 3 + x5 5 + ... And. logy = lny ln10 = 2 ln10 ⋅ (1 2 ⋅ ln y ) => logy = 0.869 ⋅ ( 1 2 ⋅ ln y ...
WebIt was actually for ease of calculations, when we didn't have digital calculators. ... Writing a log without a base is implied that it has base 10. log(100) = log_10(100) = 2 The other "exception" is the natural log, which you don't write with a base. 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.
WebSep 2, 2024 · Solution 1. For logs you are basically in for Taylor series methods, supplemented by whatever values you have available in tables or memorized.

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. Now consider solving log749 l o g 7 49 and log327 l o g 3 27 ...
