Anumber which precedes a variable and that can be expressed in the form a/b (where a and b are integers) is called a coefficient.

The answer is: Rational coefficient.

The explanation for this answer is shown below:

1. By definition, a rational number has the form where is the numerator and is the denominator. The numerator and the denominator are integers.

2. By definition, integers numbers includes positive numbers, negative numbers and zero.

3. Keeping the information above on mind, you can conclude that the answer is: Rational coefficient.

4. For example:

is a rational coefficient.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
