Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
<h3>
Answer: Choice A) 50</h3>
For two numbers x and y, the geometric mean is G = sqrt(x*y)
In this case, x = 25 and y = 100, so
G = sqrt(x*y)
G = sqrt(25*100)
G = sqrt(2500)
G = 50
Answer:

Step-by-step explanation:
We have been given an expression
. We are supposed to combine like terms for our given expression.
We can see that
are like terms as both of these terms have x variable.
Similarly,
are like terms as both are constant.
Upon combining like terms, we will get:


Therefore, our required expression would be
.
Answer:
A
Step-by-step explanation:
