## Example Questions

Explanation:

### Example Question #271 : Gre Subject Test: Math

Explanation:

Now we put each of these together and combine like terms:

### Example Question #81 : Algebra

Explanation:

Take i (the square root of -1) out of both radicals then divide.

### Example Question #11 : Operations On Complex Numbers

Explanation:

Take out i (the square root of -1) from both radicals and then multiply. You are not allowed to first multiply the radicals and then simplify because the roots are negative.

Make i squared -1

### Example Question #11 : Operations On Complex Numbers
