Pre-algebra 8 Reassessment Practice Checkpoint 2.1

According to exponent rules, when we raise a power to a power we _______ the exponents.

• add
• subtract
• multiply
• divide

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

According to exponent rules, when we divide the same bases, we _______ the exponents.

• add

• subtract

• multiply

• divide

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

According to exponent rules, when we multiply the same bases, we _______ the exponents.

• add

• subtract

• multiply

• divide
