Textbooks are stored on two shelves. Each self is 0.72meters long. Each textbooks is 30 millimetres wide. Can 50 texts books be stored on these shelves?

Cannot.

Step-by-step explanation:

1 shelf = 0.72m

2 shelves = 0.72m x 2 = 1.44m

1 textbook = 30 x 10^-3m = 0.03m

50 textbook = 50 x 0.03m = 1.5m

1.5 > 1.44m which means the textbook is 0.06m more than the shelves thus cannot be stored.

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
