To simplify the expression 7- √99, we need to simplify the square root of 99 first.
The prime factorization of 99 is 3 * 3 * 11. So, the square root of 99 can be simplified as √(3*3*11) = √(9*11) = √99.
Now, we can simplify the expression as 7- √99 = 7- √(3*3*11) = 7- 3√11.
Therefore, 7- √99 simplifies to 7- 3√11.
