Law of Negative Exponents

Simplify the expression using exponential notation:

Negative Exponent Law states: you must change the exponent to a positive by doing what?

• just change it to positive

• move to the bottom of fraction bar

• move it to the opposite side of fraction bar

(y⁹)^-2

• y¹⁸

• y¹¹

• 1/y¹⁸

• y⁹/2

y⁻¹¹⋅y⁵

• 1⁄y⁶

• y⁶

• -y⁶

• -1⁄y⁶

x^-3

• 1/x³

• 1/x^-3

• 3x

• 1/3x

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

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

• negative

• reciprocal

• positive

Make this negative exponent positive.
