#1**+1 **

A square root of something means that the square of the result would become the original number.

No rational number is squared to become 45. Probably the closest is 7, because 7^2=49.

The square root of 45 would be represented as √45. It's not a perfect square.

Of course, you *could * plug √45 into a calculator.

But the decimal places would go on forever.

Here's what I got when I put √45 into this website's calculator:

6.7082039324993691

It looks like the decimal places end, but the decimal places go on forever. The calculator rounded it.

These numbers are called irrational numbers.

They can't be expressed as a fraction.
