Exponentiation – Exponentiation Review

This looks like a great app that I could use in my 7th&8th grade math classes. However, one major error does not allow the correct scientific notation to be written in the exercise section. For example, when given 9,300,000, the app does not recognize 9.3 as the correct base. This is true of every example when a decimal is required in the base. Fix this error and I would give this app 5 stars!
