So solve for q
first factor q out of the summation

now, determine what the summation is

its been a while since ive done summations so i dont remember any tricks but that summation is essentially equal to

or factored to be something like this

which i believe there's a formula for
regardless using a calculator, the summation turns out to be 4/3 i think
you should definitely double check this step
so replacing the summation for 4/3, the equation is now
q*(4/3) =8
pretty easy to solve from here
divide 4/3 to both sides to get q
any questions?
8/1:3/5 (reciprocal)
8/1x5/3
=40/3

Answer:

Step-by-step explanation:
We can rewrite the fraction as

In order to rationalize the denominator of such a complex fraction, we must multiply the fraction by the conjugate of the denominator. In this case, the conjugate of the denominator would be
. Multiplying both sides of the fraction by the conjugate of the denominator would result in the fraction:
