Problem 1.20:- Round up the following up to three significant figures:
(i) 34.216
(ii) 10.4107
(iii) 0.04597
(iv) 2808

[@ratisana2390]

I am still confused the last one😑

[@BandhanaSharma]

Dear student, there is different between 281 and 2801. As we have to find our answer upto 3SF, we round off the value. But dont forget to mention the zero with 281.

[@saraswathi.g2367]

Why to add 0

[@shahabudin6722]

Same problem😂😂😂

[@anonymous-bs5yo]

Last me 5 h toh usse pehle agar odd no.hoga toh+1 and agr 5se pehle even no.h toh as it is.

[@anonymous-bs5yo]

​@@saraswathi.g2367 cz 0 without decimal after non zero no.is insignificant and it won't almost change the real value

[@BandhanaSharma]

Dear student , significant figures k rules k according, decimal k left side wala zero non-significant hota hai., uske sath wala zero b non significant aata hai, thats why humne agge wali values dekhi hai
