Can someone me on this problem? i don’t know how to do !

  (x^(11/4))(y^(5/9))

Step-by-step explanation:

The applicable rules of exponents are ...

  (x^a)(x^b) = x^(a+b)

  (x^a)/(x^b) = x^(a-b) . . . . . no surprise, since 1/x^b = x^-b

Your expression simplifies to ...

  x^((5/4) -(-5/4) -(-1/4)) · y^((1/18) -(-1/2))

  = x^(5/4 +5/4 +1/4) · y^(1/18 +1/2)

  = x^(11/4) · y^(1/18 +9/18)

  = x^(11/4) · y^(5/9)
