How to do Indices?

There are different rules when it comes to indices. First of all we will look at the example of multiplying two expressions . For example, y² x y⁴ . Here we need to do the addition rule, so add 2 and 4 to get 6. The answer is y⁶. Another example is y⁴ / y². Here we would need to use the subtraction rule, hence 4-2 is 2. So the answer is y².Another example is (y³)⁴. Here there is the use of brackets, where an index is inside as well as outside. So the multiplication method is needed, where you would have to do 3 x 4 which is 12. So the answer is y¹².
