SeraK+J why u have taken log ?? :/

 

[ibnatk]

I don't get this, SeraK+J

 

[Oreos]

The log method is correct but for students who haven't taken math (like me)
I would do

0.1/2.5 = Unct of 1/C

(first row of Q2)

correct me if I'm wrong

the 0.1 is by dividing 10 by 100 since that's the % unct

Here you go

It's a general rule as to calculate the unc for example if the question wants the unc of logA or unc of 1/A or A^2.. They are all different rules applied according the the needs of the question paper.. it's kind of like a formula .. sorry for the messy writing I'm always this way :S
