Solutions

Chapter 1.1, Problem 33E

(a)

To determine

To state: whether the inequality 6<10 is true or false.

Expert Solution

Answer to Problem 33E

  6<10 is false.

Explanation of Solution

Given information:

An inequality as 6<10 .

Formula used:

For two numbers a and b

  a<b if a>b

Calculation:

Consider the given inequality.

  6<10

Now, it is known that 6<10 .

Multiply both sides by (1) .

  6(1)<10(1)6>10

Hence, the inequality 6<10 is false.

(b)

To determine

To state: whether the inequality 2>1.41 is true or false.

Expert Solution

Answer to Problem 33E

  2>1.41 is true.

Explanation of Solution

Given information:

An inequality as 2>1.41 .

Formula used:

For two numbers a and b

  a>b if the digit after decimal places of a is numerically greater than digits after decimal place of b.

Calculation:

Consider the given inequality.

  2>1.41

Now, it is known that 2=1.414... .

Now, 1.41 can be written as 1.410

Further 4 is numerically greater than 0.

So, 1.414...>1.410

Hence, the inequality 2>1.41 is true.
