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.

Shouldn't that be 4x^3?

Okay, hope you are right!

Coefficient of x^3 is 448

Coefficient of x^5 is 0

Coefficient of x^10 is 17920
