5ã2x^3-xã18xy^2 simplify as much as possible

(5+4ã2)(3+4ã10)multiple and simplify as much as possible

  • math -

    Assuming you meant
    5√(2x^3)-x√(18xy^2)
    that is
    5x√(2x) - 3xy√(2x) = (5x-3xy)√(2x)

    (5+4√2)(3+4√10)
    = 15 + 12√2 + 20√10 + 16√20
    = 15 + 12√2 + 32√5 + 20√10
