Answer:

(p\vee q)\wedge(\neg p\vee r)\equiv(p\wedge r)\vee(\neg p\wedge q)

Explanation:

The statements are logically equivalent if they have the same truth tables. So let´s use truth tables in order to determine if they are logically equivalent or not:

The picture that I attached you shows the truth table for each case. As you can see in the highlight columns:

(p\vee q)\wedge(\neg p\vee r)\equiv(p\wedge r)\vee(\neg p\wedge q)

They are  logically equivalent because they have exactly the same truth values between each other. Hence, we can conclude that they are logically equivalent.

Or you can make use of the view button which is next to the zoom slider, which you can see at the bottom right section of the work space. Let's have a look at each of them now.

Word Views

The Print Layout View

Its the default one, and you will find this one as you open the document. It's best when you are documenting with things such as images, footers, columns headers, etc. And each of the components is going to be visible. You will hence get a view of documents, and how it looks like as per the page breaks.

The full-screen reading view is for reading purposes. It also shows how a printed page will look like.

Web Layout View

This gives us a view of how the document will look like on the web page. And the text gets wrapped to fit into the view if required.

Outline View

This helps when you want to move the sections in your documents, or if you are creating an outline.

Draft View

This will help you to quickly edit the text with the document being opened as a draft, and the headers and footers cannot be viewed in this view.
