Question

solve using 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

$\huge\sf\underline{\pink{A}\blue{N}\red{S}\green{W}\orange{E}\purple{R}}$

$\sf{(104)^3}$

$\sf{=(100+4) ^3}$

Using$\sf {=>(a+b)^3=>a^3+b^3+3×ab(a+b)}$

$\sf{=100 ^3 +4 ^3 +3×100×4(100+4)}$

$\sf=1000000+64+1200×104$

$\sf=1000064+124800$

$\sf=1124864$
