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: WebWhen we have an equation with a base e on either side, we can use the natural logarithm to solve it.
