Question 38: Perform the calculation \(\left( {3{x^4}{y^3} – 9{x^2}{y^2} + 25x{y^3}} \right):x{ y^2} \) we get

\(\left( {3{x^4}{y^3} – 9{x^2}{y^2} + 25x{y^3}} \right):x{y^2} = 3{ x^4}{y^3}:\left( {x{y^2}} \right) – 9{x^2}{y^2}:\left( {x{y^2}} \right ) + 25x{y^3}:\left( {x{y^2}} \right) = 3{x^3}y – 9x + 25y\)
