Answer:

b) −3y2−2x+1

d) −4xy+4y2−y−10

Step-by-step explanation:

b) -4x + y2 - 9 + 10 - x + 3x - 4y2

(i have just underlined, italic and made it bold to show the like terms)

-4x - x + 3x = -2x

y2 - 4y2 = -3y2

-9 + 10 = 1

-2x - 3y2 + 1

d) 0 - 20 - 5xy + 4y2 + 10 - y + xy

(i have just underlined, italic and made it bold to show the like terms, however the '-y' and '4y2' have no like terms)

0 - 20 + 10 = - 10

-5xy + xy = - 4xy

-10-4xy+4y2-y

choose the single logarithm expression that is equivalent to the one shown 1 / 3 log 3x + 2 / 3 log 3x

alexgriva [62]

Answer:

$\log (3x)$

Step-by-step explanation:

The given logarithmic expression is:

$\frac{1}{3}\log(3x)+ \frac{2}{3}\log(3x)$

This is the same as:

$\frac{1}{3}\log(3x)+ \frac{1}{3}\log(3x)^2$

$\frac{1}{3}(\log(3x)+ \log(3x)^2)$

We now apply the product rule to get:

$\frac{1}{3}\log(3x)\times (3x)^2$

$\frac{1}{3}\log (3x)^3$

We now apply the power rule to get;

$\frac{3}{3}\log (3x)=\log (3x)$
