What pattern do you see when raising a power to a power

When raising a power to a power, you can see that there is a pattern of the two powers being multiplied in order to form a new power.
For example:
If we have (x^2)^2, the simplified version would be x^4 and the pattern is shown because 2 multiplied by 2 is 4

The answer would be -3.9> -4.5
