Problem 1
What is the value of ![\[2^{\left(0^{\left(1^9\right)}\right)}+\left(\left(2^0\right)^1\right)^9?\]](http://latex.artofproblemsolving.com/6/7/6/67606c2b8141058216ca18ee5e71821458b74b01.png)
Solution
The first part can be rewritten as ![\[2^{0^{1}}=2^{0}=1.\]](http://latex.artofproblemsolving.com/6/5/f/65f791e3b5ae823aba59f11775813e81b9eb1db6.png)
The second part is ![\[(1^{1})^{9}=1^{9}=1.\]](http://latex.artofproblemsolving.com/2/8/6/286780308ed4829e01fd188354d093d804d65865.png)
