(m^4)-3/(m^-2)4
:
Assume you mean:
%28%28m%5E4%29%5E-3%29%2F%28%28m%5E-2%29%5E4%29 = %28m%5E-12%29%2F%28m%5E-8%29; exponents are multiplied
:
1%2F%28m%5E%28%28-8%2B12%29%29%29 = 1%2Fm%5E4; combine the exponents where they result in a positive
:
Do you understand that you subtract the exponents to divide, but subtracting a neg exponents results in adding it?
