Answer:

Option C

Step-by-step explanation:

$\boxed{Log \ \dfrac{a}{b}=log \ a - log \ b}\\\\\boxed{(log \ a)^b=b*log \ a}$

$\sf log_w \ \dfrac{(x^{2}-6)^4}{\sqrt[3]{x^2+8} }=log_w \ (x^2-6)^4 - log_w(x^2+8)^{\frac{1}{3}}$

$\sf = 4*log_w \ (x^2 -6) - \dfrac{1}{3}log_w \ (x^2 + 8)$

What is the probability of rolling a four then a three

spayn [35]

Answer:

$\frac{1}{36}$

Step-by-step explanation:

Total possibilities when we a roll a die at a time are 6

given we should have four for first time and then three

let us assume we rolled the dice we may get 1,2,3,4,5,6(any of these) the probability to get 4 is

PROBABILITY= $\frac{\textrm{FAVOURABLE CHANCES}}{\textrm{TOTAL CHANCES}}$

Favourable chances=1

Total chances=6

Probability= $\frac{1}{6}$

the prabability to get 4 in first roll is $\frac{1}{6}$ .

let us assume we rolled the dice for second time again we may get 1,2,3,4,5,6(any of these) the probability to get 3 is

Favourable chances=1

total chances=6

probability= $\frac{1}{6}$

the probability to get 3 in second roll irrespective of first one is $\frac{1}{6}$

the probability to get 4 in first time and then 3 is

The probability to occur both events at a time is multiplication of individual probabilities

So,

probablility to get 4 in first roll= $\frac{1}{6}$

probability to get 3 in second roll= $\frac{1}{6}$

probability to occur both at a same time is = $\frac{1}{6}$ $\times$ $\frac{1}{6}$ = $\frac{1}{36}$

81^3/4 how do i simply/?

Slav-nsk [51]

When you have something to an exponent and the exponent is a fraction it basically means the numerator is the power of the number and denominator is the root of the number.
81^3= 531441
4 root (531441)=27
if you have a graphing or scientific calculator you should be able to enter straight in 81^(3/4).

The length of a rectangle is 3.9 cm more than 3 times the width. If the perimeter of the rectangle is 32.6 cm, what are its dime

Ksenya-84 [330]

So length is 3.9 cm more than 3 times the width
perimeter is 32.6 cm
l = 3w + 3.9

P = l + l + w + w
32.6 = 3w + 3.9 + 3w+ 3.9 + w + w
combine like terms
32.6 = 7.8 + 8w
subtract 7.8 from both sides
24.8 = 8w
divide both sides by 8 to isolate w
3.1 = w

so we solved that the width is 3.1 cm
to find the length
l = 3.9 + (3*3.1)
l = 3.9 + 9.3
l = 13.2

The dimensions:
Length is 13.2 cm
Width is 3.1 cm

Hope this helps :)
