If you are given equation (2x^4+(1/x^3))^7, how do you find the constant term without having to expand it all? You dont have a calculator and you only have 10 minutes.
I must say I don't understand, I mean, there are two values which you can use to make it be x^0 individually but do I have to combine both x in order to then solve for k? and what does that 7 over the k mean?
Edit: more accurately, what did you do and where can I learn how to do it and understand it?
