The square root of a number is always going to be done like this. If 50 isn't a square root, what are the square root numbers multiplied by something else to make 50
25 is a square root because of 5 times 5 is 25
√25 x 2 = 50
Next carry out the 5 outside the square root and you would get
5√2 = √50
5√2 is your answer
