True or false? When n is a negative integer, n-n=0. Justify your response

1 answer:

7 0

This would be true. It is a trick question if you didn't pay attention to the negative. Just try substituting the n s for negative integers. For example:
-4--4. The negatives rule each other out and then -4+4=0.

Alex wrote the expanded form for the number 165.038 as 100+60+5+30+8. Was he correct? If not give expanded form.

oksano4ka [1.4K]

We have the next number

$165038$

The expanded form of the number is

$100000+60000+5000+30+8$

Also, we can verify that Alex was incorrect because if we do the sum of the expanded form that Alex calculated we obtain

$\begin{gathered} 100+60+5+30+8=203 \\ \text{And }203\ne165038 \end{gathered}$

Finally, the correct answer is

$100000+60000+5000+30+8$
