Subtract 75–√−45–√ .(1 point)
The difference is
.
There's an error in the expression "√−45–√" as the square root of a negative number is not defined in the real number system. Could you please provide a different expression to solve?
To subtract 75 - √(-45) - √, we need to simplify the expression first.
The square root of a negative number is imaginary, so √(-45) cannot be simplified directly.
We can rewrite the expression as 75 - √(-1 × 45) - √.
Next, we can simplify the square root of a negative number by using the imaginary unit "i". The square root of -1 is equal to "i" (i.e., √(-1) = i).
So, we have 75 - i√45 - √.
Therefore, the difference is 75 - i√45 - √.
To subtract two numbers, you need to simplify each expression separately and then subtract them.
Let's simplify each expression step by step:
1. Simplifying the number 75:
There is no simplification needed since 75 is already in its simplest form.
2. Simplifying the square root of -45:
Since the square root of a negative number is not a real number, we can't simplify it in the real number system.
Therefore, we can say that the expression cannot be simplified any further.
Now, let's subtract the two expressions:
75 - √(-45)
Since we cannot simplify the expression further, the final answer is 75 - √(-45).
