When a problem is asking us to multiply expressions, what do we do with exponents of like bases?

• add them

• multiply them

• subtract them

• do nothing to them

When a problem asks us to divide expressions, what do we do with exponents with like bases?

• add them

• multiply them

• subtract them

• do nothing to them

When an expression asks us to raise it to a power, what do we do with the exponents?

• add them

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

• Just make the exponent positive. Example: $x^{-3}=x^3$

• Create a fraction with the base on the bottom and a positive exponent. Example: $x^{-3}=\frac{1}{x^3}$

• Write no solution if there is a negative exponent

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

Anything raised to the power of 0 is equal to...

• 1

• 0

• It depends on the number

• Undefined
