Help please! Will pick the Brainliest. (sorry if it’s sideways)

KatRina [158]

$(x^2y^8)^\frac{2}{3}=x^{2\cdot\frac{2}{3}}y^{8\cdot\frac{2}{3}}=x^{\frac{4}{3}}y^{\frac{16}{3}}=x^{1\frac{1}{3}}y^{5\frac{1}{3}}=x^1x^\frac{1}{3}y^5y^\frac{1}{3}=xy^5\sqrt[3]{x}\sqrt[3]{y}=\boxed{xy^5\sqrt[3]{xy}}$

Answer B)

$\frac{1}{3}\left(\frac{2}{15}x-\frac{2}{3}\right)>x+\frac{1}{5}\quad|\cdot3\\\\\\\frac{2}{15}x-\frac{2}{3}>3x+\frac{3}{5}\quad|\cdot15\\\\\\2x-\frac{30}{3}>45x+\frac{45}{5}\\\\2x-10>45x+9\\\\-10-9>45x-2x\\\\-19>43x\quad|:43\\\\\boxed{x$

Answer B)

$\sqrt{14xy}\cdot\sqrt{12}\cdot\sqrt{30y}=\sqrt{14\cdot12\cdot30}\cdot\sqrt{xy^2}=\sqrt{2\cdot7\cdot3\cdot4\cdot2\cdot3\cdot5}\cdot\sqrt{xy^2}=\\\\=\sqrt{2^2\cdot3^2\cdot2^2\cdot5\cdot7}\cdot\sqrt{xy^2}=2\cdot3\cdot2\cdot\sqrt{35}\cdot y\cdot\sqrt{x}=\boxed{12y\sqrt{35x}}$

How do u write 1.2 as a fraction

Ivahew [28]

Split the number into its whole number component and decimal component.

for the decimal component, 0.2 is the same as 2/10

Find the GCF of both 2 and 10 and that would be 2

divide both the numerator and denominator by the GCF

simplify and you get 1/5

Lastly combine the whole number component with the fraction and your answer would be 1 1/5.

Can I see how long division works on these? pls no sketchy links

alexandr1967 [171]

Answer:

Step-by-step explanation:

11) First write in decreasing exponential terms and fill in blanks with zeros.

Our goal is to eliminate all term in the dividend by subtraction

________________

2v - 2 | 2v³ - 16v² + 0v + 13

we see that 2v needs to be multiplied by 1v² to eliminate the first term

v²

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v²

multiply your estimate by your divisor and subtract from the dividend.

bring down the next term and repeat.

v² -7v

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v

repeat again

v² - 7v - 7

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v + 13

-(-14v + 14)

-1

and remainder gets put over the divisor and appended

v² - 7v - 7 - 1/(2v - 2)

13) Same process

5a + 1 | 40a³ - 12a² - 39a - 5

8a²

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

8a² - 4a

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(-20a² - 4a)

-35a - 5

8a² - 4a - 7

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(20a² - 4a)

-35a - 5

-(-35a - 7)

8a² - 4a - 7 + 2/(5a + 1)
