Question

How to get to a negative exponent

Answer 1

The negative sign on an exponent means the reciprocal. Think of it this way,

just as a positive exponent mean repeated multiplication by the base, a negative exponent means repeated division by the base.

Example

So 2^ (-4)= 1 / (2^4)=1/(2*2*2*2)=1/16

So that answer would be 1/16
