Well, since 4^1=4 and 4^2=16 I guess the answer must be between 1 and 2 So pick your poison.

I would just substitute and solve to see which fits best... 4^20 is way more than 12 4^2 is 16 4^0.5 is square root of four is 2 4^0.33 is the cube root of 4 is 1.6 or so

Doesn't it make sense that x would have to be between 1 and 2? Only one of your choices is between 1 and 2

maybe I just confused you with my stuff... the square root of something is the same as raising it to the 1/2 power the fifth root is the same as raising to the 1/5 power... and so on \[\sqrt{x} = x^{1/2} and \sqrt[5]{x} = x^{1/5}\]
