Please show YOUR work.

5³ means 5 x 5 x 5
so if you multiply 5³ by 5² it's natural to get $$5^5 $$ right?
think about it.
5 x 5 x 5. what happens if you multiply it by 5 two more times?
5 x 5 x 5 x 5 x 5

Do you know how scientific notation works? I agree with @tkhunny please tell us what you don't get!
