Someone please solve this rational exponent equation plss

n=81

Step-by-step 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!
