Respuesta :

we have the expression

[tex]5x\sqrt[]{28x^5}+8x^3\sqrt[]{7x}[/tex]

we know that

28=(2^2)(7)

x^5=(x^4)(x)

substitute in the expression above

[tex]\begin{gathered} 5x\sqrt[]{7\cdot2^2\cdot x^4\cdot x}+8x^3\sqrt[]{7x} \\ \text{Simplify} \\ 5\cdot x\cdot2^{}\cdot x^2\sqrt[]{7\cdot x}+8x^3\sqrt[]{7x} \\ 10x^3\sqrt[]{7x}+8x^3\sqrt[]{7x} \\ 18x^3\sqrt[]{7x} \end{gathered}[/tex]
