Answer 1

do you mean by hand or by computer if possible?

by hand: consider it variable by variable. start with the constants first:

[(4^21)*(21^3)*(3^5)]/[(6^19)*(28^6)*(14^9)]

then do r, s then t

Answer 2

But I can't use calculator. I dont want to do all those operations. There isnt a shorter way?

Answer 3

i don't think so. seems like a long problem
