Remember that . Do you know what to do now?
I have the following problem;
Differentiate with respect to x;
y = (2x^5) - (3x^(1/4)) - (4/(x^7))
Now, I get that 2x^5 becomes 10x^4, and that 3x^(1/4) becomes 3/(4x^(3/4)), but what about the last part of the problem: 4/(x^7)?
Also, once I have figured that out, how do I get the final answer? Am I going in the right direction with this?
Pointing me in the direction of the techniques needed to answer the question would be appreciated more than just a direct answer.
Many thanks
Ahhh! Cheers Prove it. I had an inkling that it had something to do with that. I was aware that x^(-y) was equivalent to 1/(x^y), but somehow it didn't click that this could be done with numbers on top larger than 1. Silly of me really.
So, taking that into account, the answer to the whole problem would be:
(10x^4) - (3x^(1/4)) - (-28x^(-8))
Is this correct? Or is there another step when the problem is in the form y = (function) - (function) - (function)?
