It is 2*sqrt(5).
No, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.

No, nor is it a real number. The square root of minus 54 is equal to the square root of plus 45, times i.
Square root of 45 times square root of 45 = 45
You can always add radicals, but you can't simplify unless the radicands have a common factor. For example, the square root of 20 plus the square root of 45 equals 2 times the square root of 5 plus 3 times the square root of 5, which is 5 times the square root of 5.
45 is the square root of 2,025 (45 x 45 = 2025).
The square root of 45 in simplest form is 3sqrt(5). You take the 2 roots from 45 (5 and 9) and find out the square root of 9 is 3, while the square root of 5 is still just square root 5.
