We use identity no.4 here..
103 × 106= (100+3) × (100+6)
Identity 4: (x+a) (x+b)= x^2+ (a+b)x +ab
= (100+3) × (100+6)= 100^2 + (6+3) 100+ 6×3
=10000+900+18
=10918
10918 is the answer.. Hope u found the answer helpful.. :)

Answer:
103*106=(100+3)(100+6)
by using identity( X + a )(x + b)=x²+(a+b)x+ab..
=100²+(3+6)100+3*6
=10000+9*100+18
= 10918...
hope this helps u
