What is [tex]3^3[/tex] and [tex]12^3[/tex] divided by 2, minus 388, plus 33, and then subtract 2 again?

Also, provide the lowest common multiple of these numbers.

Answer :

= (3^3 + 12^3)/(2 - 388 + 33 - 2)
cube each numerator; subtract/add denominators working left to right

= (27 + 1728)/(-355)
add numerators

= 1755/(-355)
simplify by 5; negative can go in front of fraction

= -351/71


ANSWER: -351/71

Hope this helps! :)
