( 1 ):- ( 18 )^3
use identity : -
( a+ b )^3
= a^3 + 3a^2b + 3ab^2 + b^2
add it by taking carry to the next digit if there is .
here , a = 1 , b = 8
18^3 = 1 / 24 / 192 / 512 = 5832
(2) :- ( 18 )^2
use identity :-
( a + b )^2 = a^2 + 2ab + b^2
here a = 1 ,b = 8
18^2 = 1 / 16 / 64 = 324
(3 ) :- ( 19 )^3
use same identity: -
which I used in question (1 )
here a = 1 , b = 9
= 1 / 27 / 243 / 729 = 6859
