Anything with a zero exponent is 1. Positive exponents tell how many times to multiply a base number. Negative exponents tell how many times to divide a base number.
Negative exponents are the reciprocals of positive ones.
10^2 = 100
10^1 = 10
10^0 = 1
10^-1 = 1/10
10^-2 = 1/100
3^2 = 9
3^1 = 3
3^0 = 1
3^-1 = 1/3
3^-2 = 1/9

Can you have negative exponents in the denominator?
You can have negative exponents anywhere. When they are in the denominator, they are equivalent to positive exponents in the numerator of a fraction.
How do you solve exponents?
You sole exponents by multiplying the hole number by the exponent.
How do you change powers with negative exponents to powers with positive exponents?
by doing reciprocal
How do you figure out negative exponents?
They are the reciprocals of the positive exponents. Thus, x-a = 1/xa
How will you simplify expressions with negative exponents to get positive exponents?
A negative exponent becomes positive in the reciprocal. So if you have a number a^x where x is negative, then, a^x = 1/(a^-x) and, since x is negative, -x is positive.
