For this case we have the following expression:
 [tex] \frac{10x^5y^{12}}{-5x^{-2}y{-6}} [/tex]
 Rewriting the expression we have:
 [tex] \frac{-2x^5y^{12}}{x^{-2}y{-6}} [/tex]
 Then, by properties of exponents we have:
 "In a division, if we have the same base, the exponents are subtracted"
 We have then:
 [tex]-2x^{5-(-2)}y^{12-(-6)} -2x^{5+2}y^{12+6} -2x^{7}y^{18} [/tex]
 Answer:
 An expression that is equivalent is:
 [tex]-2x^{7}y^{18}[/tex]
