Answer 1

Answer:

Great! How miraculous the invention of computer is.

Answer 2

Answer:

What a great miraculous event the invention of computer is!

Explanation:

In conversion from simple sentences into exclamatory sentences, we take verb at the end of the sentence. Generally, when there is "a" comes in sentence, more times we use 'what' instead of 'how'.

For Example :

(1) Rahul is a good batsman.

Ans : What a good batsman Rahul is!

(2) You are kind hearted person.

Ans : How kind hearted person you are!

In above, examples we use "what" because there was "a" in sentence, but "how " because there is not "a" in second sentence.
