first simplify before doing difficult operations
divide by 5 ---> (45/4) y^4 =1
this yields y^4 = 4/45 = 0.08889 s ---->y^4 = 0.088889
this is equivalent to y = (0.08889)^1/4
If you have a very simple machine you can take twics the square root
With the canculatrice of my PC
I enter the number,
press x^y
enter 1/4= 0.25
and i have the result 0.546

Enter "225"
Press the " y^x " button*
Press ".25" (or for something not obvious, 14/23 say, enter "(", "14", "÷", "23" and ")" )
Press Enter
*Any scientific calculator has a y-to-the-x button.
