  • (18xu^(2)-20x^(4)u^(3)/(-3x^(4)u^(3))

    = (18xu^2)/(-3x^(4)u^(3)) - 20x^(4)u^(3)/(-3x^(4)u^(3)) [following the rule - (a+b)/c = a/c + b/c]

    = (18/-3)*(x/x^4)*(u^2/u^3) - (20/-3)*(x^4/x^4)*(u^3/u^3) [following the rule abc/def = a/d*b/e*c/f]

    = -6*(1/x^3)*(1/u) + (20/3)*1*1

    = -6/x^3u + 20/3 (Ans)

  • (18xu^2 - 20x^4u^3) / -3x^4u^3

    2xu^2(9 - 10x^3u) / -3x^4u^3

    2(9 - 10x^3u) / -3x^3u

    (18 - 20x^3u) / -3x^3u
