(19 z^12)/( 27 z^8)

OpenStudy (cwrw238):

there are no common factors of 19 and 27 whats z^12 / z^8 ?

OpenStudy (waleed_imtiaz):

write z^12-8=z^4.... so (19/17)z^4

OpenStudy (cwrw238):

not quite its 27 not 17

OpenStudy (waleed_imtiaz):

I am just solving the powers........ the variables are same..... so If I move the variable z from denominator to numerator then it will be z^-8.... So... Z^4 will come
