Answer:
The answer is 100.
Step-by-step explanation:
155 × 155 × 155 − 55 × 55 × 55 ÷ 155 × 155 + 155 × 55 + 55 × 55
It can also be written as :
(155)³ − (55)³ (155)²+ 155 × 55 + (55)²
We know that a³− b³ = (a − b) (a² + ab + b²) then
Denominator is cancelled out and answer become.
⇒ (155 − 55) = 100
∴ The answer is 100.
