+6sqrt%2818%29+
to find a square root of a number you have to find the prime factors of said number
18 = 3* 3 * 2
+6sqrt%283%2A3%2A2%29+
When rooting out the number take out only the ones that are a pair.
And write them only once.
+6%2A3sqrt%282%29+
Multiply the two numbers outside the root
+18sqrt%282%29+
