You can use the change of base formula to get
and also
In general, the change of base formula is
Answer:
Option (b) is correct.
The expression is equivalent, but the term is not completely factored.
Step-by-step explanation:
Given : a student factors to
We have to choose the correct statement about from the given options.
Given is factored to
Consider
Using algebraic identity,
comparing and b = 4, we have,
Thus, the factorization is equivalent but we can simplify it further also, as
Using algebraic identity,
Thus,
Can be written as
Thus, the expression is equivalent, but the term is not completely factored.
Option (b) is correct.
Yes he does. If you cut something 6 times you make 7 pieces
- (2x + 2) - 1 = -x - (x + 3)
-2x - 2 - 1 = -x - x - 3
-2x - 3 = -2x - 3
This is an identity and x can be any value
