Question

if p = a²b³cd1/2 and percentage error is a,b,c and d are 1%, 2%, 3% and 4% respectively. find percentage error in p ?​

Answer 1

Answer:

13

Explanation:

∆p/p* 100 = 2*∆a/a*100 + 3*∆b/b*100 + ∆c/c*100 + 1/2*∆d/d*100

∆p/p*100 = 2*1 + 3*2 + 3 + 1/2*4

∆p/p*100 = 2 + 6 + 3 + 2

∆p/p*100 = 13

Therefore percentage error in p is 13.
