Question

Determine the product at the greatest four digits and the greatest
number of five digits. (use distributive property)​

Answer 1

Answer:

i) 999900

ii) 99899001

Step-by-step explanation:

i) the greatest four digit number is 9999 and the smallest 3 digit number is 100

9999×100 = (9000+900+90+9)×100 = 900000+90000+9000+900 = 999900

ii) the number of 5 digits is 99999 and the greatest number of 3 digits is 999

99999×999 = (90000+9000+900+90+9)×(900+90+9)

= 90000×900+90000×90+90000×9+9000×900+9000×90+9000×9+900×900+900×90+900×9+90×900+90×90+90×9+9×900+9×90+9×9

= 99899001
