Q. Evaluate the summation below.\newline4p=03(9p2p2) 4 \sum_{p=0}^{3}\left(9 p-2 p^{2}\right) \newlineAnswer:
  1. Substitute Values: Write down the series explicitly by substituting the values of pp from 00 to 33 into the expression (9p2p2)(9p - 2p^2).\newlineFor p=0p = 0: (9×02×02)=0(9\times 0 - 2\times 0^2) = 0\newlineFor p=1p = 1: (9×12×12)=92=7(9\times 1 - 2\times 1^2) = 9 - 2 = 7\newlineFor p=2p = 2: (9×22×22)=188=10(9\times 2 - 2\times 2^2) = 18 - 8 = 10\newlineFor 0000: 0011
  2. Calculate Sum: Add the results of the series to find the sum.\newlineSum = 0+7+10+90 + 7 + 10 + 9\newlineSum = 2626
  3. Multiply by 44: Multiply the sum by 44, as indicated by the 44 in front of the summation symbol.\newlineFinal Answer = 4×Sum4 \times \text{Sum}\newlineFinal Answer = 4×264 \times 26\newlineFinal Answer = 104104
