104 ^3 - 100+4^3

Using identity

a+b ^3 -. a^3 +b^3+3ab(a+b)

(100)^3 + (4)^3 +3 .100.4(100+4)

1000000+64+1200(100+4)

1000000+1264(100+4)

1001264 +126400+5056

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$\sf {=>(a+b)^3=>a^3+b^3+3×ab(a+b)}$

$\sf{=100 ^3 +4 ^3 +3×100×4(100+4)}$

$\sf=1000000+64+1200×104$

$\sf=1000064+124800$

$\sf=1124864$
