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
