comment Compute $\int _{\frac{4}{5}}^2\:f^{-1}\left(x\right)dx$
Yes İt could be .Thanks for comment. I just wanted to give a hint how to approach for such problems.

reviewed Approve $\lim_{x\to\infty}{f(x)}=\lim_{x\to\infty}{g(x)}\Rightarrow\lim_{x\rightarrow\infty}{\frac{f(x)}{2^x}}=\lim_{x\rightarrow\infty}{\frac{g(x)}{2^x}}$?

You are welcome.

comment Binomial Theorem of Differentiation?
Yes . It will work you can use that method to prove the multinational but it will has longer terms. You may try to find the coefficients of $e^{xh}e^{yh}e^{zh}=e^{(x+y+z)h}$. Good luck

comment To evaluate $\int_0^{+\infty} \frac{\;\mathrm dx}{\sqrt[3]{x^3+a^3}\sqrt[3]{x^3+b^3}\sqrt[3]{x^3+c^3}}$
@Noam D. Elkis I think that you mistyped $x^3 = 1/t$, $dx = -t^{-2/3} dt/3$ . I have updated it as $dx = -t^{-4/3} dt/3$ . Thanks a lot for your great answer.

I have updated @Noam D. Elkies . Thanks a lot for your answer. I have noticed a mistake after your the change of variables . It should be $dx = -t^{-4/3} dt/3$ . Best Regards
