Maria spent 3/7 of her money on books 1/4 on pen and 1/8 on magazine and had $11 left how much did she have before buying this things

The correct answer is ($) 56.

Step-by-step explanation:

All you have to do is find the common denominator. In this case, 56, because it is divisible by 7, 4, and 8.

You can verify this by setting your target $11 left over.

3/7 of 56 is 24.

1/4 of 56 is 14.

1/8 of 56 is 7.

Add these all together (24+14+7) and you get 45.

56-45 = $11.

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
