Can someone please help me I have no idea how to do these equations!!!!!!!!

Question

anonymous · Answer

$$\frac{ x \frac{ 7 }{ 2 } }{ x \frac{ 2 }{ 5 } }$$

mathstudent55 · Answer

Are the fractions exponents?

anonymous · Answer

I think I'm supposed to subract 7-2 and 2-5 which would equal $$x\frac{ 5 }{ 3 }$$

anonymous · Answer

yes they are exponents.

mathstudent55 · Answer

$ \Large {\dfrac{ x ^{\frac{ 7 }{ 2 }} }{ x ^{\frac{ 2 }{ 5 } }}}$

Use the rule: $ \dfrac{x^m}{x^n} =  x^{m - n} $

Since the exponents are fractions, you need a common denominator to subtract them.

anonymous · Answer

so then it would be x^5/3

guys is it just me or is latex not showing up?

mathstudent55 · Answer

$\Large {\dfrac{ x ^{\frac{ 7 }{ 2 }} }{ x ^{\frac{ 2 }{ 5 } }}}$

$ \Large = x^{\frac{7}{2} - \frac{2}5} $

$ \Large = x^{\frac{5}{5}\frac{7}{2} - \frac{2}{2}\frac{2}5} $

$ \Large = x^{\frac{35}{10} - \frac{4}{10}} $

$ \Large = x^{\frac{31}{10}} $

@genius12 Latex is working for me.

anonymous · Answer

That can't be the answer.
