Question

Write the expression using only positive exponents. Assume no denominator equals zero.

Answer 1

• 
  `\cfrac{x^(13)}{y^3}`

-------------------------------------

Given expression:

• 
  `\cfrac{(x^5y^2)^2}{x^(-3)y^7}`

Rewrite it as follows, to get only positive exponents:

• 
  `\cfrac{(x^5y^2)^2}{x^(-3)y^7}=\cfrac{x^(10)y^4}{x^(-3)y^7}=\cfrac{x^(10+3)}{y^(7-4)}=\cfrac{x^(13)}{y^3}`
