To simplify the expression 7 – √5 – 4 – √5, we can combine like terms.

First, let's look at the numbers outside the square root, which are 7 and -4. We can combine them by subtracting:

7 - 4 = 3

Next, let's look at the numbers inside the square root, which are √5 and √5. We can also combine them by subtracting:

√5 - √5 = 0

Putting it all together, the simplified expression is 3 – 0, which is equal to 3.

So, 7 – √5 – 4 – √5 is equal to 3.
