(x+y)^3 = x^3 + 3x^2y + 3xy^2 + y^2

(90+3)^3 = 90^3 + 3(90)^2(3) + 3(90)(3)^2 + (3)^3

               =   737640

Answer 2

Answer:

ans:970301

Step-by-step explanation:

(a-b)³=a³+b³-3a²b+3ab²

(100-1)³=(100)³+(1)³-3(100)²(1)+3(100)(1)²

           =1000000+1-30000+300

           =1000301-30000

            =970301
