Dropping less than two inches per mile after emerging from the mountains, a river drains into the ocean. one day's discharge at its mouth, 9.6 trillion gallons, could supply all of country a's households for six months. based on this statement, determine how much water an average household uses each month. assume that there are 200 million households in country a.

We are given the following data:

total discharge = 9.6 trillion gallons

number of household = 200 million

number of months = 6 months

So the average use of each household per month is:

average use = (9.6 trillion gallons) / (200 million households * 6 months)

average use = 8,000 gallons / household / month

So each household uses 8,000 gallons per month

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
