Question 1013461

I can use the numbers 0, 1, 2, and 6. 
I have to use each number and can only use each number once. 
I can use any math formula or operation (add, subtract, functions, roots, powers, etc.) 
How do I get the number 20? or 21? 
Thanks.

{{{20 + 1^6)}}} ----> {{{20 + 1}}} ----> {{{highlight_green(21)}}}
