Writing a fraction as an expression using a negative exponent other than -1

Question

1/16

It says i need 30+ characters but that is the only question i have so i am filling up the space with this text -_-

Answer 1

If I understand the question correctly you mean to do the following 1/16=(16)^(-1) but also 1/16=1/(4^2)=4^(-2) and hence, you may write the fraction 1/16 as 4^(-2).
