Solve without using logarithms
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 … WebExample. Solve 5x+2 =4x 5 x + 2 = 4 x. In general we can solve exponential equations whose terms do not have like bases in the following way: Apply the logarithm to both sides of the equation. If one of the terms in the equation has base 10 10, use the common logarithm. If none of the terms in the equation has base 10 10, use the natural logarithm.

WebTo solve exponential equations without logarithms, you need to have equations with comparable exponential expressions on either side of the "equals" sign, so you can compare the powers and solve. In other words, you have to have " (some base) to (some power) equals (the same base) to (some other power)", where you set the two powers equal to ... WebAug 3, 2013 · In this post and Part 4 of this series, I discuss how the log table can be used to compute logarithms and (using the language of past generations) antilogarithms without a calculator. In Part 5, I’ll discuss my opinions about the pedagogical usefulness of log tables, even if logarithms can be computed more easily nowadays with scientific calculators.
WebWe learn how to calculate logarithms of decimals and fractions as well as how to deal with cases for which the input value isn't an obvious power of the base.
