#### Solutions

Chapter 1.4, Problem 106E

a.

To determine

## Find the form of the following algebraic expressions:  x+1+1x

Expert Solution

A+B

### Explanation of Solution

Calculation:

Here, we have:

x+1+1x

Hence, it has the form A+B , as it is the sum of two expressions i.e., x and 1+1x .

b.

To determine

Expert Solution

AB

### Explanation of Solution

Calculation:

Here, we have:

(1+x2)(1+x)3

Hence, it has the form AB , as it is the product of two expressions i.e., (1+x2)and(1+x)3 .

c.

To determine

Expert Solution

A13

### Explanation of Solution

Calculation:

Here, we have:

x4(4x2+1)3

Now, we can rewrite as:

[x4(4x2+1)]13

Hence, it has the form A13 , as it can be written as the power of another expression.

d.

To determine

Expert Solution

A/B

### Explanation of Solution

Calculation:

Here, we have:

121+x1+1+x2

Hence, it has the form A/B , as it can be written as the quotient of two other expressions.
