Question

Evaluate (104) power 3 using suitable identity

Answer 1

(104)³
(100+4)³
(100)³+4³+3×400(100+4)
= 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$\sf {=>(a+b)^3=>a^3+b^3+3×ab(a+b)}$

$\sf{=100 ^3 +4 ^3 +3×100×4(100+4)}$

$\sf=1000000+64+1200×104$

$\sf=1000064+124800$

$\sf=1124864$
