Answer:
n=81
Explanation:
We have the equation
. To isolate the variable n, we must first divide each side by -4. This would give us
=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
, or simplified, n=81. Hope this helps!
