Using indices first law, you can multiply the two d units together. #3k^4*6d^(6+3)*j^4# and thus the final answer would be #18k^4d^9j^4#

Explanation:

The trick is to put the d units together. #6d^3*d^6# would equal to #6*d^(3+6)=6d^9#

Grouping using brackets where appropriate to highlight the relationships.

#(3xx6)(k^4)(d^6d^3)(j^4)#

#18k^4d^9j^4#
