Which is the simplified form of the expression ((2^-3)(x^-3)(y^2) / (4^-2)(x^4)(y^6))^2

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

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.
