What steps he uses to solve the problem on the video? <span style="font-family: Arial,Helvetica,sans-serif;">- Jimmy Chang puts a2 which value is 3 plus the b2 which is number 4 equal c2 that is the number we have to figure it out. <span style="font-family: Arial,Helvetica,sans-serif;">- After, he multiplies 3x3 that gives 9 plus 4x4 which is 16 equal c2 <span style="font-family: Arial,Helvetica,sans-serif;">- 9+16 is 25 equal c2 <span style="font-family: Arial,Helvetica,sans-serif;">- he takes the square on both sides and the result is that c is 5
