Question

How do you write nine to the yth power in exponential form?

Answer 1

Nine to the `y^(th)` power means that `9` is multiplied by itself `y` times. So, `9` iis the base and `y` is the exponent: `9^y`

The syntax used in Socratic for writing exponents is like this:
hash 9 ^ y hash. More details about writing mathematical symbols in Socratic can be found here: http://socratic.org/help/symbols
