Question

Someone please solve this rational exponent equation plss

Answer 1

Answer:

n=81

Step-by-step 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!
