Question

Andre and Elena knew that after 28 days they would have 228 coins, but they wanted to find out how many coins that actually is. Andre wrote: 228 = 2 • 28 = 56. Elena said, “No, exponents mean repeated multiplication. It should be 28 • 28, which works out to be 784.” Do you agree with either of them? Explain your reasoning.

Answer 1

Answer:

I don't agree with any of them

Step-by-step explanation:

When you have an exponent, you use repeated multiplication for the exponent and you multiply it repeatedly by the number of the base. ex: 3*11 You would do 11 x 11 x 11 = 1331
