Each page of a photo album holds 3 rows of 4 square photos. the area of each photo is 25cmsquared .there is 2cm space between photos and a 3cm border around the group of pictures. what are the dimensions of one page of the photo album

Each photo is square-shaped and its area is 25 sq. cm.

So, side of each photo is

Let's first calculate the width of the page.

Width = Left and right border length + sum of lengths of the sides of 4 photos + spaces between 4 photos

         = (2 x 3) + (4 x 5) + (3 x 2) (Note that 3 spaces between 4 photos)

          = 6 + 20 + 6 = 32 cm.

Hence, the width of the page of the photo album is 32 cm.

Now, let's calculate its height.

Height = Top and bottom border length + sum of lengths of the sides of 3 photos + spaces between 3 photos (Note that there are 3 rows in every page)

         = (2 x 3) + (3 x 5) + (2 x 2) (Note that 2 spaces between 3 photos)

          = 6 + 15 + 4 = 25 cm.

Hence, the height of the page of the photo album is 25 cm.

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
