Answer:
- same: 30×40 = 1200
- different: 20×50 = 1000
Step-by-step explanation:
Same: 30×40 = 1200 . . . . . 2 zeros in the factors; 2 in the product
Different: 20×50 = 1000 . . . 2 zeros in the factors; 3 in the product
__
Same: 0.3×0.4 = 0.12 . . . . no zeros in the factors; no zeros in the product
Different: 0.2×0.4 = 0.08 . . . no zeros in the factors; 1 zero in the product after the decimal point
_____
For a product, the number of zeros will be different if the combined factors of the numbers increase the number of factors of 10 beyond the sum of the factors of 10 of the numbers being multiplied.
<u>Example</u>: neither 2 nor 5 has a factor of 10, but their product does.
__
For a product that is a decimal fraction, the number of leading zeros will increase if the product of the mantissas of the numbers is less than 10. The number of trailing zeros will increase under the conditions discussed above. (0.25×0.4 = 0.100)
_____
<em>Additional comment</em>
Here, the term "mantissa" is used to refer to the portion of the number written in scientific notation that multiplies the power of 10.

Use distributive property: a(b - c) = ab - ac

Answer:\
When countries are at war, the general rule is that civilians should not be targeted and I <u>support </u>this notion.
<h3>The Concept of War</h3>
- War is fought by nations to assert dominance and achieve certain conditions.
- War is fought by soldiers who pick of weapons to engage in war.
Civilians should therefore not be targeted because they have not picked up weapons to engage in the fight and so cannot be said to be targets. It makes no sense to leave the person you are fighting and who wants to fight you, to fight those who are not interested in fighting.
In conclusion, civilians should not be targeted.
