Question

evaluate using suitable identity :(104)³ .
*please also mention the identity used*​

Answer 1

(100+4)^3

(a+b)^3=a3+b3+3ab(a+b)

(100)^3+(4)^5+3(100)(4)(100+4)

1000000+64+3(400)(104)

1124864

Answer 2

Step-by-step explanation:

Given,

(104)³ = (100 + 4)³

since, (a + b)³ = a³+b³+3ab(a + b)

Where, we have to put in our equation

a = 100 and b = 4

= (100)³ + (4)³ + 3(100)(4)(100 + 4)

= 1000000 + 64 + 1200(100 + 4)

= 1000000 + 64 + 120000 + 4800

= 1124864 Ans.
