Answer: The correct answer is: " 3 " .
_______________________________
Step-by-step explanation:
_______________________________
The problem given is:
_______________________________
Evaluate: log 2 base 8 .
_______________________________
Rewrite as: " 
" ;
_______________________
Take note of the following definition of a logarithm:
_______________________
" 
" ; ↔ " 
" ;
_______________________
in which: 
refers to the "base" ;
refers to the "argument" ;
refers to the "exponent" ;
______________________________
As such:
" "
⇔ " 
" ; Solve for "x" ;
_______________
Note:
2⁰ = 1 ;
2¹ = 2 ;
2² = 2 * 2 = 4 ;
2³ = 2 * 2 * 2 = 8 .
___________________
→ " " ;
→ " 
" ; since: " 
" ;
→ as such: " x = 3 " ;
______________________
Thus:
"log 2 base 8 " ;
= 
.

Answer:
(A)74
Explanation:
Let her average score on the last two tests = x.
The six scores will now be: 82,78,87,73, x and x.
Since the average score for her first six chemistry tests = 78
We then solve for x.
Her average score for the last two tests is 74.
7 x *cross multiply
-- = --
11 121
11x 847 *divide
--- = -----
11 11
x = 77
Answer:
Step-by-step explanation:
The strange thing about the greatest integer function is that the number you are evaluating the function at is not actually the number unless its an integer. The rule is to round down, ALWAYS, if you are dealing with a value of x that is not an integer. In other words, you are NOT evaluating the function at 8.6, you have to round down to 8 and evaluate it there. 8 - 5 = 3
