Answer # 1

Ex. for 5^3, press 5, then "yx" (beneath "OFF" button), then the power (3), then press =... 5 --> yx --> 3 --> = --> 125. Hope this helps!

Answer # 2

The carrot key (exponent key) is on the very first column from left to right. It is the 5th key on the row from bottom up or top to bottom. Both will give you the same key. Try it. Type 2^3 it should give you 8.
