A construction company is repaving a damaged road. So far, they have repaved a total of 8,747 centimeters of the road. Today, they repaved 2,138 centimeters of the road. About how many centimeters of the road had they repaved before today?

previously repaved= 6,609cm

Step-by-step explanation:

Giving the following information:

So far, they have repaved a total of 8,747 centimeters of the road. Today, they repaved 2,138 centimeters of the road.

To calculate the number of centimeters repaved, we need to use the following formula:

Total centimeters= repaved today + previously repaved

8,747= 2,138 + previously repaved

6,609=previously repaved

the answer is b i just did that

step-by-step explanation:

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
