why the exponents can not be negative
When multiplying numbers with exponents, you add the exponents.
property of negative exponents
Positive exponents: an = a*a*a*...*a where there are n (>0) lots of a. Negative exponents: a-n = 1/(a*a*a*...*a) where there are n (>0) lots of a.
They can be written as reciprocals with positive exponents. For example, 5-7 = (1/5)7
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
Negative exponents are used to represent 1 divided by an a base to a specific exponent.
why the exponents can not be negative
Negative exponents indicate that the number for which the exponent applies to should be placed under one. Ex: 2^(-3) also can be expressed as 1/(2^3) or 1/8. So, to eliminate the negative exponent, simply place the number (and the accompanying exponent) under one to make a fraction.

by doing reciprocal
3
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
Exponents that are NOT a negative exponent therefore they are mostly whole numbers kind of:)

Exactly that ... negative exponents. For example: 1000 = 103 That is a positive exponent. .001 = 10-3 That is a negative exponent. For positive exponents, you move the decimal place that many positions to the right, adding zeros as needed. For negative exponents, you move the decimal place that many positions to the LEFT, adding zeros as needed. And, the special case is this: 100 = 1.
