�ã27 + �ã12 - �ã32 - �ã8

�ã27 = �ã3*3*3 = 3�ã3

�ã12 = �ã2*2*3 = 2�ã3

�ã32 = �ã2*2*2*2*2 = 4�ã2

�ã8 = �ã2*2*2 = 2�ã2

3�ã3 + 2�ã3 - 4�ã2 - 2�ã2

Here is where I get sort of confused. Because the like terms are 3. And so Im supposed to add them and I get 5�ã3. Then I subtract the 4�ã2 - 2�ã2 and I get a 2�ã2, but its supposed to be 6.(would that be known as the index? And can indexes be negative??
