Answer:
54j + 72 + 9j and 63j + 72
Explanation:
I just simplified it
So 9(6j + 8 + 1j) can be distributed to (9)(6j) + (9)(8) + (9)(1j) which equals 54j + 72 + 9j because 9*6j = 54 , 9*8 = 72 , and 9*1j = 9j
54j + 72 + 9j can also equal 63j + 72 because 54j + 9j = 63j
I hope this helped and I hope this is close to what you wanted heh :)
