Step-by-step explanation:

[tex]x \sqrt{5x {y}^{4} } + \sqrt{405 {x}^{3} y {}^{4} } - \sqrt{80 {x}^{3} {y}^{4} } [/tex]

[tex]x \sqrt{5xy {}^{4} } + 9 x\sqrt{5xy {}^{4} } - 4x \sqrt{5xy {}^{4} } [/tex]

[tex]6x \sqrt{5xy {}^{4} } [/tex]

Answer:

[tex]x\sqrt{5xy^4} + \sqrt{405x^3y^4} -\sqrt{80x^3y^4} =[/tex]

[tex]xy^2\sqrt{5x} + 9xy^2\sqrt{5x} -4xy^2\sqrt{5x} =[/tex]

[tex]xy^2\sqrt{5x} (1 + 9 - 4) =[/tex]

[tex]6xy^2\sqrt{5x}[/tex]
