Add `4.00 xx 10^(-2) , 3.26 xx 10^(-3)` and `1 xx 10^(-6)` to the correct number of significant digits :

A

`4.3261 xx 10^(-2)`

B

`4.33 xx 10^(-2)`

C

`4.3 xx 10^(-2)`

D

cannot be calculated

Text Solution

Verified by Experts

The correct Answer is:
B
`{:(4.00 xx 10^(-2)),(0.326 xx 10^(-2) ),(0.0001 xx 10^(-2) ) (overline(4.3261 xx 10^(-2) )):}`
` = 4.33 xx 10^(-2)`
(upto two decimal places as in `4.00 xx 10^(-2)`)
