7 sqrt%2812%29+4sqrt%283%29
12 can be broken up as 4*3;
7sqrt%284%2A3%29+4sqrt%283%29
4 is a perfect square = 2, so we have;
7*2sqrt%283%29+4sqrt%283%29
Multiply 7*2=14 so we have;
14sqrt%283%29+4sqrt%283%29
Now we can add them together because they are like terms;
18sqrt%283%29
Hope you understand
