Twice the square of half of a number is x. What is the number? I know twice the square is 2x^2 but I'm not sure about the half. Also the answer is sqrt2x
2 times square of 1/2 of n=x 2 times square of n/2=x 2 times (n/2)²=x 2 times (n²)/4=x (n²)/2=x if solving for the number times 2 both sides n²=2n sqrt both sides [tex]n= \sqrt{2x} [/tex]
