Question

simplify using the brackets by expanding any of the numbers.
(a) 28x103
(b) 98x57​

Answer 1

Step-by-step explanation:

for the first one, lets use distributive property of multiplication

∴ 28×(100+3)

28*100+28*3

2800+64

i.e 2864

for the second one, lets use distributive property of multiplication,but we will exchange the numbers  

i.e 98 *57=57*98  (closure property)

∴ by distribution we have,

57*(100-2)

57*100-57*2

5700-  114

5586
