Which expression is equivalent to ^4√16x^11y^8/81x^7y^6 ? assume x > 0 and y = 0

 For this case we have an expression of the form:
 
 To solve the problem, we must rewrite the expression using properties of exponents.
 Rewriting the expression we have:
 
 Then, by root properties we have:
 
 Then, by power properties again:
 
  
 An expression that is equivalent is:
