# Does $20n$ belong to $O(n^{1-\epsilon})$ for some $\epsilon > 0$?

I am quite new to master theorem and I would like to ask the following question for $$𝑇(𝑛)=4𝑇(𝑛/4)+20𝑛.$$ If there is a constant value like $$20n$$ does it affect the equation?

Would the equation look something like this for test case 1:

Is $$f(n) = 20n \in O(n^{log_ba-\epsilon}) \in O(n^{\log_4^4-\epsilon}) \in O(n^{1-\epsilon})$$ for some $$\epsilon > 0$$?
