To solve these problems, you need to know that you can multiply two numbers with exponents simply by adding their exponents—as long as the bases of the numbers you’re multiplying are the same! In other words, this rule says that:
2m ∗ 2n = 2m+n
The letters “m” and “n” here stand for any exponent whatsoever. And remember that the base doesn’t have to be 2 for this equation to work—it can be anything.
