Final answer:
To find the value of the expression, simplify both sides of the equation and solve for y.
Step-by-step explanation:
To find the value of the expression, we need to simplify it.
We can simplify ( y^(3/2)y^(-1/2) ) as y^((3/2) - (1/2)) = y^(2/2) = y. Next, we simplify (1/3) / (1/4y + 1) as (1/3) * (1 / (1/4y + 1)).
Multiplying both numerator and denominator by the reciprocal of (1/4y + 1), we get (1/3) * (4y + 1) / 1 = (4y + 1) / 3.
So, we have y = (4y + 1) / 3. To solve for y, we can cross-multiply, giving us 3y = 4y + 1. Then, we can subtract 4y from both sides, which gives -y = 1.
Finally, dividing both sides by -1, we find that y = -1.
