Question

evaluate using suitable identity: (104)^3​

Answer 1

Step-by-step explanation:

(100+4)³

using the identity

(a+b)³=a³+b³+3ab(a+b)

(100+4)³=100³+4³+3*100*4(100+4)

=1000000+64+1200*104

=1000000+64+124800

=1124800+64

=1124864

Answer 2

Answer:

134816

Step-by-step explanation:

as in the question it is given that (104)³.

so, firstly make the equation in the simplest term⇒(100+4)³

(a+b)³=a³+b³+3ab(a+b)

so now, put down the values, (100)³+(4)³+(3×100×4)(100+4)

10000+16+(1200×104)

10000+16+124800

10000+124816
