Using order of operations, we can see we should first solve for the exponents, and then multiply the exponent values by each other.
3²×
9×243
2187
Another way to solve this is to add the exponents together and simply do
. We can only do that in this case, however, because the values are being multiplied by each other.
Either way we solve, we will get 2187 as our final answer.
