Question

Simplify the following expression completely, where x

Answer 1

Explanation:

`x \sqrt{5x {y}^(4) } + \sqrt{405 {x}^(3) y {}^(4) } - \sqrt{80 {x}^(3) {y}^(4) }`

`x \sqrt{5xy {}^(4) } + 9 x\sqrt{5xy {}^(4) } - 4x \sqrt{5xy {}^(4) }`

`6x \sqrt{5xy {}^(4) }`

Answer 2

`x√(5xy^4) + √(405x^3y^4) -√(80x^3y^4) =`

`xy^2√(5x) + 9xy^2√(5x) -4xy^2√(5x) =`

`xy^2√(5x) (1 + 9 - 4) =`

`6xy^2√(5x)`
