Joseph was given the exponential expression of (x^3 y^-4)^3 to simplify. After using his exponent properties, he calculated x^9 y^-12 as his answer. Is Joseph's answer written in its simplest form?

what is the answer?

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.
