Answer:
$$\sqrt[3]{27x^6y^4}=3 x^2\sqrt[3]{y^4}$$
Step-by-step explanation:
![\sqrt[3]{27x^6y^4}= \sqrt[3]{3^3x^6y^4}\\\sqrt[3]{27x^6y^4}=\sqrt[3]{3^3} \sqrt[3]{x^6} \sqrt[3]{y^4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D%20%5Csqrt%5B3%5D%7B3%5E3x%5E6y%5E4%7D%5C%5C%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D%5Csqrt%5B3%5D%7B3%5E3%7D%20%5Csqrt%5B3%5D%7Bx%5E6%7D%20%5Csqrt%5B3%5D%7By%5E4%7D)
therefore,
![\sqrt[3]{27x^6y^4}=3 x^2\sqrt[3]{y^4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B27x%5E6y%5E4%7D%3D3%20x%5E2%5Csqrt%5B3%5D%7By%5E4%7D)
Did u attach something? Or what question do u need help in?
Answer:
The percent increase of her collection is 60%
Step-by-step explanation:
Divide 24 by 15 to get your answer which is 1.6. Since the decimal is .6 and it is one digit behind the decimal, you can safely assume it is 60%
When you are 10 years ,your sister will be 10/2 = 5 years
10 - 5 = 5
Your sister is 5 years younger to you
After 90 years your age will be 100 years.
After 90 years your sister's age will be 5+90 = 95 years
Correct option A

Answer:
(5/6, 8/5)
Step-by-step explanation:
We multiply the second equation by 2, and then add the equations together.
12x+15y=34
-12x+10y=6
------------------
25y=40
We divide by 25 on both sides, and get that y = 8/5. We substitute y into either of the equations.
-6x +5(8/5)=3
Do the multiplication.
-6x+8=3
Subtract 8 from both sides.
-6x=-5
Divide by -6 on both sides.
x=5/6.
