Subtract 75–√−45–√ .

Answer 1

To subtract 75 – √(-45) – √, we need to calculate the square root of -45 first.

The square root of a negative number is not a real number, as there is no real number that, when squared, equals a negative number. Therefore, √(-45) is undefined in the real number system.

So, the expression 75 – √(-45) – √ cannot be simplified further.
