Q. Evaluate the summation below.\newline2t=03(4t+t2) 2 \sum_{t=0}^{3}\left(4 t+t^{2}\right) \newlineAnswer:
  1. Write Summation Formula: Write down the summation formula that needs to be evaluated.\newlineWe need to evaluate the summation 2t=03(4t+t2)2\sum_{t=0}^{3} (4t + t^2).
  2. Expand Summation: Expand the summation by plugging in the values of tt from 00 to 33.2t=03(4t+t2)=2[(40+02)+(41+12)+(42+22)+(43+32)]2\sum_{t=0}^{3} (4t + t^2) = 2[(4\cdot0 + 0^2) + (4\cdot1 + 1^2) + (4\cdot2 + 2^2) + (4\cdot3 + 3^2)]
  3. Calculate Terms: Calculate the terms inside the brackets.\newline2[(4×0+02)+(4×1+12)+(4×2+22)+(4×3+32)]=2[(0+0)+(4+1)+(8+4)+(12+9)]2[(4\times0 + 0^2) + (4\times1 + 1^2) + (4\times2 + 2^2) + (4\times3 + 3^2)] = 2[(0 + 0) + (4 + 1) + (8 + 4) + (12 + 9)]
  4. Simplify Terms: Simplify the terms inside the brackets.\newline2[(0+0)+(4+1)+(8+4)+(12+9)]=2[0+5+12+21]2[(0 + 0) + (4 + 1) + (8 + 4) + (12 + 9)] = 2[0 + 5 + 12 + 21]
  5. Add Numbers: Add the numbers inside the brackets.\newline2[0+5+12+21]=2[38]2[0 + 5 + 12 + 21] = 2[38]
  6. Multiply Sum: Multiply the sum by 22. \newline2[38]=762[38] = 76
