A number ,x, rounded to 2 decimal places is 15.38, write the error interval

error interval is 15.375 ≤ x < 15.385

Step-by-step explanation:

An error interval shows the range of value a number could have taken before rounded or truncated. It is expressed using inequality as range showing the upper bound and the lower bound. It shows a range of values in which a number could be before it was rounded. The upper bound shows the highest value the number can be while The lower bound shows the lowest value the number can be.

x = 15.38 to 2 decimal places.

The lower bound = 15.375

The upper bound = 15.385

Therefore the error interval = 15.375 ≤ x < 15.385

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
