Law of Exponents Negative and Zero Rule

Anything raised to a power of zero is always: 

• 0

• 1

• itself

• negative

(y⁹)^-2

• y¹⁸

• y¹¹

• 1/y¹⁸

• y⁹/2

Evaluate the expression using the quotient rule.

• x¹³

• x⁵

• x³⁶

• x^-5

Simplify the expression in exponential form:
134⁰

• 0

• 134

• 1

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.

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

• 4
• 4x
• 1
• 0

Can you leave a negative exponent in your answer?

• YES

• NO

• 3
• 0
• 1
• 1/3

• 1/-9.7
• 1
• -9.70
• -9700
