Answer:
A coefficient is the number next to a letter. It's used to multiply a variable. If there is just a variable then the coefficient is 1. For example 6x.
Step-by-step explanation:
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.

8/8 is an improper fraction
8/8 * 5/8 = 5/8......it is not less then, it is equal
V = d/t = 8.8 miles/[80/60] hours = 6.6 miles/hour
t = d/v = d/6.6
Answer: d/6.6, where d is the number of miles to run.
