The answer is
(a^(6))/(b^(5))

The expression is:
( a^(2) b^(-3) )/( a^(-4) b^(2) )

Using the rule:
( x^(a) )/( x^(b) )= x^(a-b), we can rewrite the expression:
( a^(2) b^(-3) )/( a^(-4) b^(2) )=a^(2-(-4))b^(-3-2)= a^(2+4) b^(-5) =a^(6) b^(-5)

Using the rule:
x^(-a) = (1)/( x^(a) ), we can rewrite
a^(6) b^(-5):
a^(6) b^(-5)= (a^(6))/(b^(5))
