Question

evaluate the suitable idintites 3 M 92​

Answer 1

Answer:

778688

Step-by-step explanation:

according to,

(a-b)^3 = a^3 - 3a^2b + 3ab^2 - b^3

we can split 92^3 as (100-8)^3

then,

we can write in the form of identity

= 100^3 (100)^2 (8) + 3 (100)(8) - (8)^3

= 1000000-3(10000)(8)+3(100)(64) - 512

= 1000000 - 240000 + 19200-512

= 778688

have a great day
