Answer:
[tex]\sqrt{\frac{4}{x^{4} } }= 2x^{-2}[/tex]
Step-by-step explanation:
We have
[tex]\sqrt{\frac{4}{x^{4} }}[/tex] this equals to
[tex]\sqrt{\frac{2^{2} }{x^{4} }[/tex] now we are going to cancel the squares with the roots.
[tex]= \frac{2}{x^{2} }[/tex] if we want the x in the up part we just put negative the exponent
[tex]= 2x^{-2}[/tex]
