A typical example of a rational exponent and radicals is a^x/y = y√(a)^x
<h3>What is a rational exponent?</h3>
We have a rational exponent when a number is raised to a power such as x/y. In this case, we must know that; a^x/y is the same as y√(a)^x.
Now let me give you a specific example. Assuming that a write something like 5^3/2. This would be the same as saying √(5)^3.

Answer:
3) 16.2
Step-by-step explanation:
The supplement to the 115° angle on the right is 65°, the same as the angle at upper left. The vertical angles at C are the same measure, so this tells you that the two triangles FCB and ACD are similar by the AA similarity postulate. That being the case, corresponding sides are proportional:
CB/CD = CF/CA
CB = CD·CF/CA = 7.2·21.6/9.6
CB = 16.2
