73*73*73+27*27*27/73*73-73*27+27*27
⇒(73)³+(27)³/(73)²-73*27+(27)²
⇒(73+27){(73)²-73*27+(27)²}/(73)²-73*27+(27)² {∵(a+b)³=(a+b)(a²-ab+b²)}
⇒73+27
⇒100
⇒(73)³+(27)³/(73)²-73*27+(27)²

Ur Ques: 73 × 73 × 73 + 27 × 27 × 27 / 73 × 73 - 73 × 27 + 27 × 27
By BODMAS Rule,
First we put brackets (within multiplication)
= (73 × 73 × 73) + (27 × 27 × 27) / (73 × 73) - (73 × 27) + (27 × 27)
= 389017 + 19683 / 5329 - 1971 + 729
= 408700 / 4087
= 100
