An index is another name for an exponent.
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. When you have a negative exponent, you can flip it to the other side of a fraction and change the sign. In other words:x⁻ⁿ = 1/(xⁿ)For example:2⁻⁴ = 1/(2⁴) = 1/16
