If we have a base to the power of 0, then the entire answer is 1.

• False, only that base is 1

• True, the final answer is always 1

If we have a base with a negative exponent, then we...(select all that are true)

• If it is at the top of the fraction, move it to the bottom and make the power positive

• If it is at the bottom of the fraction, move it to the top and make the power positive

• Always move the negative powers to the bottom of the fraction

• Just change the power to positive and you're done
