Question

23³-17³
By using identity

Answer 1

Answer:

7254

Step-by-step explanation:

x³ - y³ = (x-y) (x²-xy+y²)

Now substitute x = 23 & y = 17

23³ - 17³ = (23 - 17) [(23)² + (23) (17) + (17)²]

             = (6) [529 + 391 + 289]

             = (6) [1209]

             = 6 * 1209

             = 7254.

Sorry for answering it late.

Hope it helps
