Given the numerical equation:

(-5-√3)^2

Simplify.

Solution:

In order to simplify the numerical equation, we need to square it first since it is enclosed with a parenthesis raised to 2.

= (-5-√3)^2

= 25- 3

25 became positive, since it is a general rule that when squaring negative numbers, the answer will be positive. Hence in the case of -3, since it is enclosed with a square root sign, squaring it means that the square root sign will be remove and the value inside the sign will not be affected.

= 25 -3

= 22

Final answer:

= 22
