multiplying exponents (question in the attachment)
simplify your answer. type exponential notation with positive rational exponents.

Step-by-step explanation:

The relevant rule of exponents is ...

  (a^b·c^d)^e = a^(be)·c^(de)

Then ...

  (m^(5/4)·n^(-4/5))^(7/3) = m^(5/4·7/3)·n^(-4/5·7/3)

  = m^(35/12)·n^(-28/15)

__

Since you want positive rational exponents, you can write this as ...

  = m^(35/12)/n^(28/15)

i believe it's a.

i'm not sure on this one, most likely correct.

y-3=-3/2(x+4)

ur very much welcome
