Subtract 75–√−4–√5.(1 point)

Answer 1

To subtract the given expression, we simplify each radical term first.

√−4 cannot be simplified because a negative number does not have a real square root. Hence, √−4= √(-1 × 4) = 2i√1 = 2i

Similarly, √5 cannot be simplified, so √5= √5

Now, we can subtract the given expression: 75 – √−4 – √5 = 75 – 2i – √5.
