For instance x2 pronounced as ecks to the minus two just means x2 but underneath as in 1 x 2 frac 1 x2 x21. A negative exponent takes us to the inverse of the number.

Most questions will ask you to solve negative exponents by expressing them as positive equations. M 0 m n n m n m n m n m n 1 since anything divided by itself is just 1. Add exponents together if the multiplied base numbers are the same.

Moving a term from the numerator to the denominator or vice versa changes the sign of the exponent. 1 5 5 5 153 1125 0008. Subtract negative exponents if the divided base numbers are the same.

Flip the base and exponent into the reciprocal then solve the denominator.
