When you see a negative exponent... (check ALL that apply)

• ... if it is in the numerator, flip it to the denominator and make the exponent positive

• ... if it is in the numerator, keep it there and make the exponent positive

• ... if it is in the denominator, keep it there and make the exponent positive

• ... if it is in the denominator, flip it to the numerator and make the exponent positive

x^-3

• 1/x³

• 1/x^-3

• 3x

• 1/3x

• 4^-2

• 1/4²

• 1/16

• all of the above

It is not proper to write answers with negative exponents. How do we "take care of" negative exponents?

• Write no solution if there is a negative exponent

• Just leave the negative exponent. It is mathematically okay.

• -6
• 8
• -8
• 1/8

According to exponent rules, if you have a negative exponent, you use the ____________________.
