What term should go in the space

Think abt it like a puzzle you see a 9 so you gotta divide it to get 3 so bam there’s ur first number 3 then you have a j^4 and when you divide exponents it’s really subtracting them so you want a j^2 then k^9 to get to k^2 would be 9-2=7 so your final answer is 3j^2k^7

Whose mistake? can you give more details to what the question is asking?
