Help with solving indefinite integral

Question

I am working on this problem, attempting to find the indefinite integral: $$\int9(\sqrt[5]{2x})dx$$ I can manage to get up to here: $$=9(2^{1\over 5})({5\over 6}x^\frac{6}{5})+C$$ But I don't know how to get to here (The Solution): $$=\frac{15x^\frac{6}{5}}{2^{4\over 5}}+C$$ If anyone could provide an explanation as to how I get from where I am, to the solution, it would be greatly appreciated!

Answer 1

write 6=2.3 then get cancel nominator 9 by denominator 3 and multiply it by present 5 in nominator you will get 15. And then handelout 2 by (2)^1/5 you will get (2)^4/5 in the denominator

Answer 2

As a gentle reminder, please note that, by the first fundamental theorem of calculus, the indefinite integral of a function is a primitive of the function. So it is better to call $\int f$ a primitive of a function $f$.

Regarding the original question, we have $\int 9\cdot 2^{1/5}\cdot x^{1/5} dx = 15\cdot 2^{-4/5}\cdot x^{6/5} +$ const.
