Answer:
The answer is 166/21, or 7 19/21
Step-by-step explanation:
First, you would set up the equation, which is:
13 1/7 - 5 5/21
Next, you would turn them into an improper fraction, which is:
92/7 - 110/21
Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:
276/21 - 110/21
Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.
216 =6^3
1,296 = 6^4
7,776 = 6^5
x = 6^f(x)
log x = log 6^f(x) = f(x)log 6
f(x) = log x / log 6 =
The correct answer is …..3, 2 1/4, 2 1/2
Answer:
10
Step-by-step explanation:
Given expression is
.
is a complex expression.
The value of<em> i </em>is –1.
By definition of absolute value, 
Now, substitute
in the above formula.
(since <em>i </em>= –1)
(since
and
)
(Square root of 100 is 10)
= 10
Hence, the value of the expression
is 10.
