Question

Using suitable identities , evaluate 56ka cube + 44ka cube

Answer 1

Answer:

Step-by-step explanation:

(56^3)+(44^3)

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

=(56+44)((56^2)+(44^2)-56*44)

=(100)(3136+1936-2464)

=(100)(2608)

=260800

Answer 2

Step-by-step explanation:

here,we use the identity(a+b){(56)^2+(44)^2-56*44

then it will,

(100)(3136+1936-2464)
