Question

Find using distributive property: (a) 728×101​

Answer 1

Step-by-step explanation:

You can simply know it just by looking or you can remember the value of root 2 and root 3

root 2 = 1.41

root 3 = 1.73

Alternatively,

Let x = 3 root 2 and y = 2 root 3

squaring both sides, we get

x square = 18 and y square = 12

Now its easier to tell which one is greater x square or y square.

Answer 2

In distributive property :-

We can write 101 as (100+1)

So, 728 × (100 + 1)

728 × 100 + 728 × 1

= 72800 + 728

= 73528
