789*789*789+211*211*211/789*789-789*211+211*211

Answer 1

the answer is 1195.82. you have to group 789*789*789, find the answer. similarly  do it for 211 also. add the two answers. then multiply 789*211 and add it to the product of 211*211. subtract this answer from the answer of 789*789. divide the first answer by this answer.

Answer 2

do this question by applying BODMAS.
first divide 211 and 789
then multiply789*789*789 and the divided answer with 789 then multiply 211 with 789 and then 211 with 211.
then add them and at last do the subtraction.
so simple.
