Anna takes 10 selfies every 12 minutes at this rate how many minutes for 25 selfie’s

30 minutes.

Step-by-step explanation:

You can make a proportion, which would be 10 selfies : 12 minutes. The second one will be 25 selfies : x minutes.

They have to be equal, since it is given that the rate stays the same. So 10:12=25:x

A proportion can be written as a fraction, so 10/12=25/x.

Cross multiply, and you get 10*x=12*25, or 10x=300.

Now divide both sides by 10 to get x=30.

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
