What does this mean? [tex]\frac{2.33*\sqrt{0.373*0.627}} {\sqrt{300} }[/tex≈0.065

Explanation:

Properly written and rendered, it means ...

The asterisk (*) is used to signify multiplication.

___

The expression is equivalent to ...

  2.33·√(0.00077957) ≈ 0.065

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
