    81a^(8) b^(20)^(1/4) 81a^8 b^5 is all I can see to do to it

    exponents with exponents multiply, for example: a^3^4 means (a^3).(a^3).(a^3).(a^3) means (a.a.a).(a.a.a).(a.a.a).(a.a.a) means a.a.a.a.a.a.a.a.a.a.a.a means 12 little a's; or, a^12

    my choices are as follows: 1/3|a^2b^5| or|3a^2b^5| or 81/a^8b^20

    81 doesnt simplify to anything other than perhaps its perfect prime factors, but what good does that do since none of the cancel out?
