Answer:

(100+4) ^3= (100) ^3+(4) ^3+3×(100) ^2×4+3×100×(4) ^2=1000000+64+120000+4800=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$\sf {=>(a+b)^3=>a^3+b^3+3×ab(a+b)}$

$\sf{=100 ^3 +4 ^3 +3×100×4(100+4)}$

$\sf=1000000+64+1200×104$

$\sf=1000064+124800$

$\sf=1124864$
