Question

Solve (102)^3 using identify. ​

Answer 1

Answer:

1061208

Step-by-step explanation:

let us rewrite (102)³ as (100+2)³

now using the identity (a+b)³ = a³+ b³+ 3ab(a+b), we get

(100+2)³= 100³+ 2³+ [(3×100×2)(100+2)]

=1000000 + 8 + ( 600 × 102 )

=1000000 + 8 + 61200

=1061208

Hence, (102)³= 1061208
