why is pp small?

(a-b) *(a-b) *(a-b)

=(a*a*a) -3*(a*a*b)+3*(a*b*b)-(b*b*b)

34000*(1-7%)*(1-7%)*(1-7%)

=34000*(1-0.07)*(1-0.07)*(1-0.07)

=34000*[(1*1*1)-3*(1*1*0.07)+3*(1*0.07*0.07)-(0.07*0.07*0.07)]

=34000*(1-0.21+0.0147-0.000343)

=34000*(0.804357)

=34*1000*(804.357/1000)

=34*804.357

=27348.138

=27348
