Question

Which of the following is equivalent to the expression below when x20?

Answer 1

A. x√x

Step-by-step explanation:

The given expression is

`\sqrt[]{x^3}+\sqrt[]{25x^3}-5x\sqrt[]{x}`

Then, it is equivalent to

`\begin{gathered} \sqrt[]{x^2\cdot x}+\sqrt[]{25x^2\cdot x}-5x\sqrt[]{x} \\ x\sqrt[]{x}+5x\sqrt[]{x}-5x\sqrt[]{x} \\ x\sqrt[]{x} \end{gathered}`

Therefore, the answer is

A. x√x
