Answer: what is your question, is this your question bro
Step-by-step explanation:
Answer: It is an associative property of addition.
Step-by-step explanation:
Since we have given that
(4+6.1)+7=4+(6.1+7)
As we know that "Associative property":

Associativity in addition means that adding three numbers and then change the order of numbers and then add it again, we will get the same answer.
So,

Hence, it is an associative property of addition.
The GCF is 
Explanation:
The GCF or greatest common factor is the factorization of two or more numbers to determine the greatest number that they have common.
The given terms are
and 
To determine the gcf of these two terms, let us find the greatest number that they have in common.
Comparing the powers of m from both the terms, we have,

Similarly, comparing the powers of n from both the terms, we have,

Also, comparing the powers of p from both the terms, we have,

Thus, the GCF of the terms
and
is
