4. Find the value of each of the following using various properties.
i. 273 x 29 + 273 x 71
ii. 8765 x 999 + 8765
iii. 2398 x 761 - 2398 x 661
iv. 12345 x 12345 - 12345 x 2345
v. 389 x 17 + 389 x 23 + 389 x 60 vi. 683 x 36 + 683 x 17 - (683 x 48) - (5 x 683)​

Answer 1

Answer:

273 x 29 + 273 x 71 = 581490

8765 x 999 + 8765 = 8765000

2398 x 761 - 2398 x 661 =  1204659280

12345 x 12345 - 12345 x 2345 = 85734676460

389 x 17 + 389 x 23 + 389 x 60 = 9686100

683 x 36 + 683 x 17 - (683 x 48) - (5 x 683)​ = 429607 - 3672 - 3415 =  35873
