How do i write expressions without any negative exponents

Turn the exponent into a fraction. For example:
3^-2 turns into 1/3^-2
Then flip the exponent so its 3^2/1

Do this for all of them, typically it works out.

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
