Question 192559
{{{(2^(-2)*a^(-3)*b^(-2) * c)/(a*b^(-2)*c^(-3))}}}
move any powers to negative exponents in the numerator, down into the denominator.
Move any powers to negative exponents in the denominator, up into the numerator. 

{{{(c * b^(2)*c^(3))/(a* 2^(2)*a^(3)*b^(2))}}}
associate and consolidate powers
{{{(b^(2)*c^(4))/(2^(2)*a^(4)*b^(2))}}}
cancel terms as appropriate (in this case there is a b^2 in both numerator and denominator, so they cancel out (b^2/b^2) is equal to 1) )
{{{(c^(4))/(2^(2)*a^(4)))}}}
