Well, to get this, you would have to multiply 7.8 by 2 or add 7.8 to 7.8, the reason you would have to do this is because the midpoint is 1/2 of the line. So 7.8+7.8=15.6.
15.6 (D) is your answer.
Hope this helped!

Answer:

Step-by-step explanation:
An exponent which is a fraction is simplified using a radical.
5/4 is a 4th root radical with an exponent of 5 on the inside.
Once written inside there will be an exponent of 4 raised to the 5th power. Power to a power rule requires that these are multiplied so the exponent on n will be 20. 16 must also be raised to an exponent of 5. See the solution below.
![\sqrt[4]{(16n^4)^5} \\\sqrt[4]{(16^5 n^{20}} \\\sqrt[4]{(16^5 n^{20}} \\32n^5](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B%2816n%5E4%29%5E5%7D%20%5C%5C%5Csqrt%5B4%5D%7B%2816%5E5%20n%5E%7B20%7D%7D%20%5C%5C%5Csqrt%5B4%5D%7B%2816%5E5%20n%5E%7B20%7D%7D%20%5C%5C32n%5E5)
