How do I solve this ?

guapka [62]

I don't like fractions, so I would turn 8/14 into a decimal.

Do 8 divided by 14 and you'll get .57

Now 8 + 0.57 = 8.57

The fraction form would be 60/7 and the mixed form would be 8 4/7

What is logs(4.7)+logs 2 written as a single log?

Ipatiy [6.2K]

ANSWER

$log_{s}(56)$

EXPLANATION

The given logarithmic expression is:

$log_{s}(4 \times 7) + log_{s}(2)$

Recall and use the product rule of logarithm

$log_{a}(b) + log_{a}(c) = log_{s}(bc)$

We apply this rule to obtain,

$log_{s}(4 \times 7) + log_{s}(2) = log_{s}(4 \times 7 \times 2)$

We multiply out the argument to get;

$log_{s}(4 \times 7) + log_{s}(2) = log_{s}(56)$

The correct answer is

$log_{s}(56)$

nCr
you have n items and how many ways are there to chose r of them

nCr= $\frac{n!}{r!(n-r)!}$
remember than n! means n times all numbers before like
3!=3*2*1, 5!=5*4*3*2*1
9 stations, how many ways are there to chose 6 of them
9C6= $\frac{9!}{6!(9-6)!}$ =
$\frac{9!}{6!(3)!}$ =
$\frac{9*8*7}{3!}$ =
$\frac{9*8*7}{3*2*1}$ =
$\frac{3*4*7}{1}$ =
84
