Negative Exponents and Fractions
When a factor is moved to the other side of the fraction bar, we
change the sign of the exponent.
Here, x ≠ 0 and y ≠ 0.
A fraction raised to a power is equal to the reciprocal of the fraction
raised to the opposite power.
Here, x ≠ 0 and y ≠ 0.
We can use these formulas to rewrite expressions using positive exponents.
