Full solution

Q. x2y(2xy27xy+5x4y) x^{2} y\left(2 x y^{2}-7 x y+5 x-4 y\right)
  1. Distribute x2yx^{2}y: Distribute x2yx^{2}y across the terms inside the parentheses (2xy27xy+5x4y)(2xy^{2}-7xy+5x-4y). To distribute, multiply x2yx^{2}y by each term inside the parentheses.
  2. Multiply 2xy22xy^{2}: Multiply x2yx^{2}y by the first term 2xy22xy^{2}.\newlinex2y×2xy2=2x3y3x^{2}y \times 2xy^{2} = 2x^{3}y^{3}
  3. Multiply 7xy-7xy: Multiply x2yx^{2}y by the second term 7xy-7xy.x2y×7xy=7x3y2x^{2}y \times -7xy = -7x^{3}y^{2}
  4. Multiply 5x5x: Multiply x2yx^{2}y by the third term 5x5x.\newlinex2y×5x=5x3yx^{2}y \times 5x = 5x^{3}y
  5. Multiply 4y-4y: Multiply x2yx^{2}y by the fourth term 4y-4y.\newlinex2y×4y=4x2y2x^{2}y \times -4y = -4x^{2}y^{2}
  6. Combine results: Combine the results from steps 22 to 55 to get the final expression. 2x3y37x3y2+5x3y4x2y22x^{3}y^{3} - 7x^{3}y^{2} + 5x^{3}y - 4x^{2}y^{2}
