Question

Solve. 4^x = 12

x ≈ 19.93
x ≈ 1.79
x ≈ 0.56
x ≈ 0.27

Answer 1

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

Answer 2

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

Answer 3

I still dont really get it... :/
