Answer:
Ambos cometas coincidirán en 2016.
Step-by-step explanation:
(The following exercise is presented in Spanish and for such reason explanation will be held in that language).
Sean y los años en los que se hacen visibles los cometas, respectivamente. Se sabe que los cometas coinciden cuando se pueden ver el mismo año, ese año estaría asociado al mínimo común múltiplo de ambos intervalos de tiempo, el cual sería igual a 72 años.

Answer:
6160
Step-by-step explanation:
If you do not understand my solution, send a picture of how your teacher does it and I will guide you in the same style as your teacher.
you have numbers: 16 28 40 77. I will write each number in each line and show its multiple numbers: Now that if you multiply the numbers I write, you get the same number. For example, 2*2*2*2 = 16 (same for the rest)
16: 2 2 2 2
28: 2 2 7
40: 2 2 2 5
77: 7 11
From the above, we pick 2*2*2*2*5*7*11 = 6160
I got that by picking a number comprised of factors that appear in at least any of the numbers 16 28 40 77
No because brackets represent multiplication, so (84)5(73)9 is actually 84.5.73.9
