4(3xy^4)^3/(2x^3y^5)^4

myrzilka [38]

Answer:

$\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}$

Step-by-step explanation:

Given the expression

$\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}$

solving the expression

$\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=4\cdot \:\frac{\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}$

$=4\:\frac{27x^3y^{12}}{16x^{12}y^{20}}$

$=4\cdot \frac{3^3}{2^4x^9y^8}$

The multiply fractions are defined as

$\:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}$

so the expression becomes

$=\frac{3^3\cdot \:4}{2^4x^9y^8}$

$=\frac{3^3\cdot \:2^2}{2^4x^9y^8}$

$=\frac{3^3}{2^2x^9y^8}$

Refining

$=\frac{27}{4x^9y^8}$

Therefore,

$\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}$

<h3>Given</h3>

36a² -24a +4

the complete factorization

<h3>Solution</h3>

You can see that 4 is a factor of all terms, so you can rewrite the expression as

.... 4(9a² -6a +1)

The first and last terms in parentheses are squares, and the second term is double the product of their square roots, so the quantity in parentheses is a perfect square. Multiplying it out tells you this is a good guess. The minus sign tells you the repeated binomial factor will be a difference.

... = 4(3a -1)²

There is no further factorization.

2/5 as a decimal show all work

larisa [96]

Answer:

0.4

Step-by-step explanation:

to convert from a fraction to a decimal, we first have to make the denominator 100

we know that 5 goes into 100 20 times ;

100 ÷ 5 = 20 ;

then we have to multiply the numerator by 20 as well because we have multiplied the bottom by 20 ;

$\frac{2}{5}$ $(\frac{20}{20})$

2 x 20 = 40 ;

= $\frac{40}{100}$

then to convert this into a decimal, divide the numerator by the denominator

40 ÷ 100 = 0.4
