Answer:
we know that
C. Commutative Property of
in this problem we have
substitute in the formula above
therefore
the answer is the option
C. Commutative Property of.
The expression given in the problem statement is:
2 + (√(5) + 7)) = (2 + √(5)) + 7
One of the properties of real numbers is associative property of addition.
If there are three real numbers a, b, and c then the associative property of addition can be depicted as:
a + (b + c) = (a + b) + c --- (1)
So considering the given problem we can compare it with the expression in (1) and infer:
a = 2, b = √(5), c = 7
Therefore we can state the expression:
2 + (√(5) + 7)) = (2 + √(5)) + 7 is an associative property of addition of real numbers
