16

Answer 6

x^16

Answer 7

@campbell_st so x^16

Answer 8

Answer 9

But its says to write your answer with a positive exponent only

Answer 10

yes... so the negative indicates a fraction

\[x^{-a} = \frac{1}{x^a}\]

now use this index law

just replace a with 16

Answer 12

So 1/x^16 is the answer
