Question

A Find the product of the largest s digit number
and the bargest B-digit numbers using distributive
Llaw.​

Answer 1

We know that the Largest five digit number = 99999

The largest three digit number = 999

According to the distributive property, a x (b - c) = (a x b) – (a x c)

Hence multiplying the largest five digit number and the largest three digit number becomes,  

99999 x 999 = 99999 x (1000-1)

Applying distributive property to the right hand side becomes,

=( 99999 x 1000)- (99999 x 1)

= 99999000 – 99999

99999 x 999 = 99899001.
