A​

Answer 1

complete this please

Solution:

The largest three digit number is 999 and the largest four digit number is 9999.

We have to find their products using distributive law.

Now, 999 × 9999

= 999 × (10000 - 1) ,

since 9999 = 10000 - 1

= (999 × 10000) - (999 × 1) ,

using distribution law

= {(1000 - 1) × 10000} - 999 ,

since 999 = 1000 - 1

= (1000 × 10000) - (1 × 10000) - 999 ,

using distributive law

= 10000000 - 10000 - 999

= 9989001

Answer 2

Answer:

99,89,001

Step-by-step explanation:

Largest 4-digit number = 9999

Largest 3-digit  number = 999

Product = 9999 x 999

             = (10000 - 1) x (1000 - 1)

             = 1000000 - 10000 - 1000 + 1

             = 99,89,001
