The rule for expressing a radical as a rational exponent is as follows:
$\sqrt[n]{x^y} = x^ \frac{y}{n}$
So, to find $\sqrt[3]{27x^2y^3z^4}$ use that rule.
The cube root of 27 is 3, so the equation will start with 3.
$3x^ \frac{2}{3} yz^ \frac{4}{3}$
Hope that helps!

What is the value of X?

rodikova [14]

Answer:

102

Step-by-step explanation:

triangle area = 180 degrees

straight line = 180 degrees

180 - 127 = 53

49 + 53 + 3rd angle = 180

3rd angle = 78

180-78 = x

x = 102

(17+4) + 9 = 17 + (4+9)

valina [46]

That's the associative property of addition

it is normally written as
(a+b)+c=a+(b+c)
which is like what you have
(17+4)+9=17+(4+9)

There are 125 people and three door prizes. How many ways can three door prizes of $50 each be distributed? How many ways can do

UkoKoshka [18]

We have been given that there are 125 people and three door prizes.

In the first part we need to figure out how many ways can three door prizes of $50 each be distributed?

Since there are total 125 people and there are three identical door prices, therefore, we need to use combinations for this part.

Hence, the required number of ways are:

$_{3}^{125}\textrm{C}=\frac{125!}{122!3!}=\frac{125*124*123}{1*2*3}=317750$

In the next part, we need to figure out how many ways can door prizes of $5,000, $500 and $50 be distributed?

Since we have total 125 people and there are three prices of different values, therefore, the required number of ways can be figured out by using permutations.

$_{3}^{125}\textrm{P}=\frac{125!}{122!}=125*124*123=1906500$
