Question

A physical quantity P blankis given by P equals fraction numerator A to the power of 3 end exponent B to the power of fraction numerator 1 over denominator blank 2 end fraction end exponent over denominator C to the power of negative 4 end exponent D to the power of fraction numerator 3 over denominator 2 end fraction end exponent end fraction. The quantity which brings in the maximum percentage error in P is

  1. A    
  2. B    
  3. C    
  4. D    

The correct answer is: C


    Quantity C has maximum power. So it brings maximum error in P
