distributive law to evaluate 317x103​

Answer 1

(i) 984 x 102

= 984 x (100 + 2)

= 984 x 100 x 984 x 2

= 98400 + 1968 = 100,368

(ii) 385 x 1004

= 385 x (1000 + 4)

= 385 x 1000 x 385 x 4

= 385000 + 1540 = 386540

(iii) 446 x 10002

= 446 x (10000 + 2)

= 446 x 10000 x 446 x 2

= 4460000 + 892 = 4460892
