WebMay 29, 2024 · It is possible to multiply exponents with different bases, but there’s one important catch: the exponents have to be the same. Here’s how you do it: 5^4 × 2^4 = ? First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. 5^4 × 2^4 = 10^4 This is why it works: WebHow to solve an exponential equation with two different bases Learn how to multiply exponents with the same base, with different bases, fractions, Solution: In the given question, the base is the same, that is, 10.
WebIn order to solve these equations we must know logarithms and how to use them with exponentiation. We can access variables within an exponent in exponential equations with different bases by using logarithms and the power rule of logarithms to get rid of the base and have just the exponent. Sample Problems (8) 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 calculate (log 5)/ (log 3).
