Question

when 4 numbers b, b^2, b^3, and b^4 were arranged in order from smallest to largest, the result is b, b^3, b^4, and b^2. Which of the following is a possible value for b?

The choices are:
1. 7/2
2. 11/6
3. 7/10
4. -2/5
5. -7/4

Answer 1

Since b^4 < b^2, b^4/b^2 < 1 so b^2 < 1
Since the odd powers are also less, b<0

So, #4
