Answer: 4
Step-by-step explanation:
We know that a plane is 2 dimensional surface that extends infinitely far.
The number of points required to define a plane = 3
Here , we have 4 points A, B, C, and D.
So, the number of possible combinations of 3 points to make a plane from 4 points = 
[
]
Hence, the greatest number of planes determined using any three of the points A, B, C, and D if no three points are collinear = 4.
He messed up step 2 he added instead of multiplying

Answer:

Step-by-step explanation:
we would like to expand the following logarithmic expression:

remember the multiplication logarithmic indentity given by:

so our given expression should be

by exponent logarithmic property we acquire:

hence, our answer is A
