Answer:

The answer is rational.

Explanation:

Given expression is :


4.56*4.5 (5 repeating)

Lets convert this in fraction form.

Suppose x = 4.555....

Multiplying by 10 on both sides;


10x=45.555

Subtracting x from 10x


9x=45.555-4.555=41

We get

x=41/9

Now multiplying 45.6 or 456/100(fraction form) and 41/9, we get 18696/900

This is rational.
