Answer:
Step-by-step explanation:
First let's find the value of 'p-q':
To find |p-q| (module of 'p-q'), we can use the formula:
Where 'a' is the coefficient of 'i' and 'b' is the coefficient of 'j'
So we have:
Now, we need to find the module of p and the module of q:
Then, evaluating |p-q|-{|p|-|q|}, we have:
Answer:
Step-by-step explanation:
In order to round to the nearest thousandth, you must observe the digit to the right of the digit in the thousandth place and then:
In this case, given the number:
You can notice that the digit to the right of the digit in the thousandth place is 9.
Since , you must round up. Then:
Finally, to express this as a single-digit times a power of ten, move the decimal point three places to the right. Then you get:
