Solutions

Chapter 1.4, Problem 106E

a.

To determine

Find the form of the following algebraic expressions:

  x+1+1x

Expert Solution

Answer to Problem 106E

  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

Find the form of the following algebraic expressions:

  (1+x2)(1+x)3

Expert Solution

Answer to Problem 106E

  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

Find the form of the following algebraic expressions:

  x4(4x2+1)3

Expert Solution

Answer to Problem 106E

  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

Find the form of the following algebraic expressions:

  121+x1+1+x2

Expert Solution

Answer to Problem 106E

  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.
