Look at this expression.
-3x6y4

x-3y-2

which of the following is the simplest form of this expression?

Multiply x and 1

The x just gets copied along.

The answer is x

x

3*x evaluates to 3x

Because of the minus sign

3x becomes - 3x

The answer is -3x

Multiply y and 2

Multiply y and 1

The y just gets copied along.

The answer is y

y

2*y evaluates to 2y

-3*x-2*y evaluates to -3x-2y

The answer is -3x-2y-2

-3*x-2*y-2 evaluates to -3x-2y-2

so the first one is right

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

step-by-step explanation:

5x+10 is the correct one

hope this
