We are simplifying the cube root of negative 16.
00:05
In order to do that, you have to break down your number, meaning do the factor tree.
00:10
So two numbers that multiply to be 16 are 2 and 8.
00:14
So 2 is prime, so i've got to keep breaking down 8, which are 2 and 4.
00:18
Again, 2 is prime, but i can break down 4 to 2 and 2.
00:24
So since i have a negative, i'm going to make, we'll talk about that later.
00:29
So since i have the cube root, that means i have to have three in a group in order to bring that outside of the radical, which i see three twos here...
