Answer :

The answer is the last one (-5x7)!

Answer:

- 5[tex]x^{7}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]\frac{a^{m} }{a^{n} }[/tex] = [tex]a^{(m-n)}[/tex]

Given

[tex]\frac{10x^5}{-2x^-2}[/tex] ( split factors into product )

= [tex]\frac{10}{-2}[/tex] × [tex]x^{5-(-2)}[/tex]

= - 5[tex]x^{7}[/tex]
