__________

Four quanties a,b,c,d are measured with percentage error

a=1%

b=2%

c=3%

d=4%

P =a^3b^2/cd

So , We know that power of a quantity is multiplied by its percentage error .

And If quantities are multiplied there percentage errors are added .

So.....

P=3(1) + 2(2)/3+4

P=3+4/3+4

P=7/7

P=1 %

rashkejahan25: ∆p/p×100={3∆a/a+2∆b/b+∆c/c+∆d/d)×100=3∆a/a×100+2∆b/b×100+∆c/c×100+∆d/d×100=3×1+2×2+3+4=3+4+3+4=14%

rashkejahan25: is it wrong?because it is in written in textbook
