Right, I just guessed that number before proving n^2+3n+1 was the form for n=4 which gives 16 + 12 + 1 = 29 for the square root of 4x5x6x7 + 1 = 841. I have a newer version of that video which is much neater than that zoom whiteboard proof which was very sloppy. Glad it helped you. Did you have to prove that for a school assignment?
Nicee
Glad you found it helpful! Just did a more recent neater version of the same thing. The zoom whiteboard feature not ideal for presenting math :)
841=29 square not 21 square. Thanks
