Simplify the radical expression 4 square root 81x^20y^8

Dimas [21]

The simplified expression is $3x^5 y^2$

Step-by-step explanation:

The radical expression to simplify is

$\sqrt[4]{81x^{20}y^8}$

We notice the following:

$81=3^4$

And using the property

$(x^a)^b=x^{a\cdot b}$

we can write:

$x^{20}=(x^5)^4$

$y^8 = (y^2)^4$

So the argument of the radical can be written as

$\sqrt[4]{(3)^4(x^5)^4(y^2)^4} =\sqrt[4]{(3x^5y^2)^4}$

And now by using the property

$\sqrt[n]{a^n}=a$

We find:

$\sqrt[4]{(3x^5y^2)^4}=3x^5 y^2$

A plastic sack contains 20 green and yellow, 14 red and yellow, and 16 orange and yellow gummy treats. How much greater is the p

noname [10]

Answer:

Probability of choosing green and yellow treat is higher than Probability of choosing an orange and yellow treat by 0.08

Step-by-step explanation:

Given -

Green and yellow gummy treats = 20

Red and yellow gummy treats = 14

Orange and yellow gummy treats = 16

Total gummy treat = 20+14+16 = 50

Probability of choosing green and yellow treat = 20/50 = 0.4

Probability of choosing an orange and yellow treat = 16/50 = 0.32

Probability of choosing green and yellow treat is higher than Probability of choosing an orange and yellow treat by 0.08

Find the area of sector JKL. Enter your answer in terms of a fraction of π and rounded to the nearest hundredth.

Anna007 [38]

Given:

The radius of the circle is 4 cm.

The angle of the sector JKL is 135°

We need to determine the area of the sector JKL

Area of the sector:

The area of the sector can be determined using the formula,

$A=\frac{\theta}{360^{\circ}} \times \pi r^{2}$

Substituting $\theta=135^{\circ}$ , $r=4$ , we get;

$A=\frac{135^{\circ}}{360^{\circ}} \times (3.14) (4)^{2}$

$A=\frac{3}{8} \times (3.14) (16)$

$A=\frac{150.72}{8}$

$A=18.84 \ cm^2$

Thus, the area of the sector is 18.84 cm²

3) Choose the prime factorization of 15. O 11,4 O 5,5,5 O 3,5 O 2, 2, 11 05.10

juin [17]

Hey there! I'm happy to help!

A prime number is a number whose only factors are one and itself. 5 is a prime number because the only whole numbers you can multiply to get 5 are 1 and 5.

Prime factorization is finding the prime numbers that multiply to make that number.

To do this, you see what numbers it divides by. 15 is divisible by 1, giving us 15. It is not divisible by 2, but it is divisible by 3, which gives us 5.

Now, we see if 3 and 5 can be factorized even more, but they cannot as they are both prime numbers. Therefore, the prime factorization of 15 is 3,5.

Have a wonderful day! :D
