Answer: \frac{x^2\sqrt{x}}{3}

Step-by-step explanation:

Here the given expression is, \sqrt{\frac{2x^5}{18} }

= \sqrt{\frac{x^5}{9} }

= \sqrt{\frac{x^5}{9} }

= \sqrt{\frac{x^4.x^1}{9} }  (because x^{m+n}= x^m.x^n )

=\frac{x^2\sqrt{x} }{3}

Thus,\sqrt{\frac{2x^5}{18} } =\frac{x^2\sqrt{x} }{3}

\sqrt{\dfrac{2x^5}{18}}=\sqrt{\dfrac{2}{18}\cdot x^2\cdot x^2\cdot x}=\sqrt{\dfrac{1}{9}\cdot x^2\cdot x^2\cdot x}=\sqrt{\dfrac{1}{9}}\cdot\sqrt{x^2}\cdot\sqrt{x^2}\cdot\sqrt{x}=\\\\\\=\dfrac{1}{3}\cdot x\cdot x\cdot\sqrt{x}=\boxed{\dfrac{x^2\sqrt{x}}{3}}

Answer: (x^{\frac{2}{7}})(x^{\frac{3}{5}})

Step-by-step explanation:

If you took the nth root of x, it is the same as raising x to the power of 1/n. Therefore:

\sqrt[7]{x^{2} }  = (x^{2} )^{1/7} = (x^{\frac{2}{7}})\\\sqrt[5]{x^{3} }  = (x^{3} )^{1/5} = (x^{\frac{3}{5}})

And multiply:

(x^{\frac{2}{7}})(x^{\frac{3}{5}})
