%28%28-2%29%5E%28-3%29+-+3%29%2F%28%28-3%29%5E%28-2%29-3%5E0+%29

recall the rules: a%5E%28-m%29=1%2Fa%5Em and a%5E0=1

so, you have:

%28%28-2%29%5E%28-3%29+-+3%29%2F%28%28-3%29%5E%28-2%29-3%5E0+%29....apply rules

%281%2F%28-2%29%5E3+-+3%29%2F%281%2F%28-3%29%5E2-1+%29.....%28-2%29%5E3=%28-2%29%28-2%29%28-2%29=-8

%281%2F%28-8%29+-+%283%2A8%29%2F8%29%2F%281%2F9-1+%29

%28-1%2F8+-+24%2F8%29%2F%281%2F9-9%2F9+%29

%28-25%2F8%29%2F%28-8%2F9+%29...........use the rule %28a%2Fb%29%2F%28c%2Fd%29=ad%2Fbc

%28-25%2A9%29%2F%288%28-8%29+%29

%28-225%29%2F%28-64%29

3.515625.........round it to two decimal places

3.52
