Answer 1

Explanation:

a). Given expression in the question is,

`(13822* 623)/(14)`

Exact value of the expression will be,

`(13822* 623)/(14)=615079`

b). By using approximations to 1 significant figure,

13822 ≈ 10000

623 ≈ 600

14 ≈ 10

615079 ≈ 60000

Now use the expression,

`(13822* 623)/(14)=(10000* 600)/(10)`

= 60000
