Sigma notation and its application to binomials with exponents
Hi
I have a certain problem that I hope you can help me out with it is a binomial like in the examples however the internal terms already have exponents. (4x3-1/root x)8. Sorry not very clear, tablet has limited keyboard but in words, open bracket four x to the power of three minus one over the square root of x, closed bracket to the power of eight. They are asking for the coefficient of the xterm to the power of 3, 5 and 10 respectively.

Hi;
Is this what you are talking about?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Shouldn't that be 4x^3?

You should really wait till I edit the post, which I have now done.

Okay, hope you are right!
Coefficient of x^3 is 448
Coefficient of x^5 is 0
Coefficient of x^10 is 17920
