39.392800 convert it into 4 significant figutes​

Answer»

Answer:

39.39

Step-by-step explanation:

This MEANS that there must be only 4 significant figures in the number

Given number contains 8 significant figures

hence we have to decrease the last four figures by rounding off

here

if the figure is less than 5 then the left number remain unchanged

but if the last figure is 5 or greater than 5 then the left digit increase by 1

Let

apply this in the above number

both zeros are less than 5 , hence digit 8 will remain unchanged... THOUGH we remove both zeros

and the number will become 39.3928

now digit 8 is greater than 5 ... hence the left digit will become 3

and number become 39.393

let

the digit 3 is less than 5

hence we can remove it without any CHANGE in the left digits ...

this way the number will become 39.39

in the last solution there are only 4 significant figures

if this answer helped you...

then rate me 5 STARS...
