the exponent of a number tells us how many times we should multiply the base.
For example, 82, 8 is the base, and 2 is the exponent.
We know that 82 = 8 × 8.
A negative exponent tells us, how many times we have to multiply the reciprocal of the base.
Consider the 8-2, here, the base is 8 and we have a negative exponent (-2).
8-2 is expressed as 1/82 = 1/8×1/8.
