Answer:

n=81

Explanation:

We have the equation
-4n^(-1/2) =-4/9. To isolate the variable n, we must first divide each side by -4. This would give us
n^(-1/2)=1/9. Now, we need to get rid of the exponent =-1/2. To do this, we must raise both sides of the equation by the reciprocal of -1/2, or -2. This gives us the equation
(n^(-1/2))^(-2)=1/9^(-2), or simplified, n=81. Hope this helps!
