Question 1206799
<font color=black size=3>
Let {{{w = x^(2020)}}}


Multiply both sides by x
{{{wx = x^(2020)*x = x^(2020+1) = x^(2021)}}}



The original equation can be rewritten like this
{{{(wx+wx+wx)/(w) = 30}}}


{{{(3wx)/(w) = 30}}}


{{{3x = 30}}}
At this point it's fairly easy to see that x = 10.
