You need to be more specific. I can't answer until I know what you want to multiply. I understand that it is about the video and square roots but this is still not enough information to go off of. To find the square root...If it is a perfect square root it will be easier and it will have one numberan example of a perfect square root is:sqrt of 16 is 4 because 4 x 4 = 16sqrt of 144is 12because 12 x 12 = 144If it is not a perfect square like the sqrt of 12:think of some numbers that multiplied equal 126 x 2 3 x 4we are going to use (3 x 4) because 4 is a perfect square.now it is the sqrt of (3x4) then you separate them to the sqrt of 3 x the sqrt of 4since 4 is a perfect square it becomes a two sqrt of 3 x 2 and then we have2 sqrt 3 which is the same as above only written differently.
