Answer:
190%
Step-by-step explanation:
$1.56 is close to nearly 2x the value of $0.87
You can start by multiplying $0.87 by 2 to get $1.74
Now put $1.56 / $1.74
This gets you 0.89655172
By rounding this, you can get to 0.90
Move the decimal places two spots over to get a percentage = 90%
Since the eggs didn't decrease in value, you can add the 100% from the beginning of the problem.
100+90=190%

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)
Answer:
3x^4-18x^3+27x^2-12x
Step-by-step explanation:
Multiply the second paréntesis for each term of the first parentage
3x^2×(x^2-2x+1)-12x×(x^2-2x+1)
Multiply parentage by 3x^2
3x^4-6x^3+3x^2-12x×(x^2-2x+1)
Multiply the parentage by -12x
3x^4-6x^3+3x^2-12x^3+24x^2-12x
Group similar terms
3x^4-18x^3+27x^2-12x
