Виконайте дії:

1) x^(\3)/4 + 〖2x〗^(\4)/3 = (3x+8x)/12 = 11x/12;
2) 〖5b〗^(\1)/14 – b^(\2)/7 = (5b-2b)/14 = 3b/14;
3) m^(\3)/8 – n^(\4)/6 = (3m-4n)/24;
4) 4^(\y)/x –3^(\x)/y = (4y-3x)/xy;
5) m^(\3)/4n + m^(\2)/6n = (3m+2m)/12n = 5m/12n;
6) c^(\3)/b – d^(\1)/3b = (3c- d)/3b;
7) a^(〖ab〗^2 )/b^2 + 1^(\1)/(ab^4 ) = (a^2 b^2+1)/(ab^4 );
8) 11^(\3b)/5a – 〖2c〗^(\1)/15ab = (33b-2c)/15ab;
9) m^(\m)/abc + c^(\c)/abm = (m^2+c^2)/abcm.
