Flip the fraction top-to-bottom, and delete the minus sign from the exponent.
Why not? An exponent is just like any other number.
It can be either.
A negative exponent is put into fraction form because it is a way of writing powers of fractions or decimals.
Any non-zero fraction is the same as its reciprocal raised to the power of -1.So 3/4 = (4/3)-1 and there you have your negative exponent!
Flip the fraction top-to-bottom, and delete the minus sign from the exponent.
The reciprocal of a^(-x/y) is 1/a^(x/y). The fact that the exponent is a fraction makes no difference.
Why not? An exponent is just like any other number.
A fraction
It can be either.
Because a number to the exponent 0 = 1 and any lesser exponent decreases the value.
A negative exponent is put into fraction form because it is a way of writing powers of fractions or decimals.
Not necessarily. If the exponent is not an integer then it is not a polynomial.
One-thousandth, 1 x 10-3
(2a3)(10a5)/4a1
1/243
This is a procedure used to help people who are new to negative exponents. A negative exponent, when moved to the other side of the fraction, becomes a positive exponent and beginners are more comfortable with working with positive fractions.
