Can you please explain how to do this and give me the answer so next time I know how to do it. Square root with -15 in it and square root with -4 in it Simplify using i

15i and 4i

Step-by-step explanation:

An easy way to do this is to take the negative inside the square root like , take the absolute value -6 absolute value=6 and times it by i.  So now it becomes 6i
