Answer:
Step-by-step explanation:
Given:
1/2(ln(xx + yy) − ln(zz))
Now,
From the properties of log function,
1) n × ln(x) = ln(xⁿ)
and,
2) ln(A) - ln(B) = 
applying the properties in the given equation
we get the above equation as:
( using the property 2 we get (ln(xx + yy) − ln(zz) =
or
⇒
( using the property 1 i.e n × ln(x) = ln(xⁿ) )
expression as an equivalent expression with a single logarithm is

Answer: THIRD OPTION.
Step-by-step explanation:
The Associative property of addition states that when three or more numbers are added, it does not matter how they are grouped, the sum is the same. Then:

Based on this and having the expression
, we can apply the Associative property as following:

Therefore, the expression that illustrates the Associative property of addition is the one shown in the Third option.
