Power to a Power Law states: keep the base the same and do this to the exponents.

• multiply

• add

• subtract

• divide

CHECK ALL THAT ARE TRUE: When rewriting a power with a negative exponent, so that it no longer has a negative exponent...

• You must keep the exponent negative.

• You must write the reciprocal of the base.

• You must change the sign of the exponent.

• You must change the sign of the whole power term.

• You must switch the base with the exponent.

Answer explanation

When simplifying a power term with a negative exponent...

-You must write the reciprocal of the power

-You must change the sign of the exponent

You must NOT:

-...keep the exponent negative, because this would not be simplifying the expression.

-...change the sign of the whole power term, because this changes the base of the power term and will no longer be an equivalent expression.

-...switch the base with the exponent, because this changes the base and exponent of the power term and will no longer be an equivalent expression.
