Answer :

Given:

The percentage error in a i.e.

The percentage error in b i.e.

The percentage error in c i.e.

The percentage error in d i.e.

(Rule: The relative error in a physical quantity raised to the power k is the k times the relative error in the individual quantity)

Multiplying both sides by 100 will make each quantity % and thus we can directly substitute the given values to find ΔP/P % or percentage error in P.

Since number of significant digits in ΔP/P are 2, P should also have 2 significant digits.

P = 3.8 (rounded off to first decimal place)
