Answer 1

here Is your answer

Answer 2

let a be any +ve integer and take b=3,

by euclid s division lemma ,

a=bq+r,0=/<r<b

a=3q+r,0=/<r<3

this implies ,

r=0,1,2

when r=0

a=3q

on cubing,

a^3=27q^3

=9×3q^3

=9m,where m=3q^3

when r=1,

a=3q+1

on cubing,

a^3=27q^3+27q^2+9q^2+1

=9×3qcube+ 3 q square+qsquare+1

=9m,where m= 3 q cubee.....+1

when r=2

a=3q+2

on cubing

a cube=27q cube plus 54 q square +36 q +8

= 9( 3q^3+6q^2+4q)+8

=9m+ 8

where m=3q....+8
