x to the negative 3/7 power times x to the positive 5/3 power, all over x to the 4/5 power?
:
%28x%5E%28-3%2F7%29%2Ax%5E%285%2F3%29%29%2F%28x%5E%284%2F5%29%29
:
x%5E%28-3%2F7+%2B+5%2F3+-+4%2F5%29; combine the exponents: -3/7 + 5/3 - 4/5
:
x%5E%28-45%2F105+%2B+175%2F105+-+84%2F105%29Using a common denominator: -45/105 + 175/105 - 84/105
:
x%5E%2846%2F105%29 resulting exponent: 46/105
