Question 473328
When you write exponents use the ^ sign. Also, post only one problem per post; this makes tutors more likely to answer your question.


For all these problems use the identities


*[tex \LARGE (a^b)^c = a^{bc}]


*[tex \LARGE (a^b)(a^c) = a^{b+c}]


*[tex \LARGE \frac{a^b}{a^c} = a^{b-c}]


You have to make sure the base of the exponent is the same before you apply these identities.
