You mean situation, when a^b < a.
There are two ways:

But exponent function a^b has to be increasing so a>1
So first solution: a>1 and 0<b<1. Examples:

and second way:

Exponent function a^b has to be decreasing, so 0<a<1
Second solution: a<1 and b>1. Examples:
Answer:
8,12 and 16
Step-by-step explanation:
7 pounds = 16 pounds and 1 pound = 6 pounds and 16 ounces.
(6 pounds + 16 ounces) minus (5 pounds + 10 ounces) = 1 pound + 6 ounces
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
