Question

What’s the square root of 50?

Answer 1

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

Answer 2

Simplify √50.

Factor out 50.

√50 = √(5 x 5 x 2)

Note that there are 2 5's inside the parenthesis. Two of the same number when multiplied would become a whole number:

√(5 x 5) = 5

√50 = √(5 x 5 x 2) = 5√2

5√2 is your answer
