Where do u even use square root lol

Well if you're a builder square root comes in handy for buying material... Hypotenuse of a triangle.

Thz but i will not use it after i graguate

Depends on your degree and career. You'd be surprised who all uses math and the degree of mth they use.

I will not okay
And ik that I will use it if I am an engineer or a archetech
