Step-by-step explanation:
Powers of 10 is a very useful way of writing down large or small numbers.
Instead of having lots of zeros, you show how many powers of 10 will make that many zeros.
When you work with small numbers, you should use the negative powers of 10. Just remember for negative powers of 10, move the decimal point to the left. For example,
![0.36=3.6\cdot 10^{-1}\ [\text{Move the decimal point one place to the left}]\\ \\0.036=3.6\times 10^{-2}\ [\text{Move the decimal point two places to the left}]\\ \\0.0036=3.6\times 10^{-3}\ [\text{Move the decimal point three places to the left}]\\ \\...](https://tex.z-dn.net/?f=0.36%3D3.6%5Ccdot%2010%5E%7B-1%7D%5C%20%5B%5Ctext%7BMove%20the%20decimal%20point%20one%20place%20to%20the%20left%7D%5D%5C%5C%20%5C%5C0.036%3D3.6%5Ctimes%2010%5E%7B-2%7D%5C%20%5B%5Ctext%7BMove%20the%20decimal%20point%20two%20places%20to%20the%20left%7D%5D%5C%5C%20%5C%5C0.0036%3D3.6%5Ctimes%2010%5E%7B-3%7D%5C%20%5B%5Ctext%7BMove%20the%20decimal%20point%20three%20places%20to%20the%20left%7D%5D%5C%5C%20%5C%5C...)
When comparing small numbers, write these numbers in scientific notation (only one non-xero digit must be before point) and then
- if the powers of 10 are the same in compared numbers are the same, just compare the numbers which are multiplied by these powers of 10. For example,
because powers are the same (-6) and 
- if the powers are different, then the smaller is power, the smaller is number (number with the smaller negative power has more places after decimal point). For example,
because 
To get the reciprocal, simply flip the numerator and denominator. The reciprocal of 3/10 is 10/3.
Answer:
A. A cylinder with diameter 8 units
Step-by-step explanation:
∵ The <u>line</u> m is the <em>central axis</em>
So the radius is 4 units. ∴ Diameter is 8 units.
∵ The picture is a <em>rectangle</em>.
[ The <em>rectangle rotates</em> are its side to form a <em>cylinder</em> ]
So a cylinder with diameter 8 units.
The answer is A.
Answer:
I think I did this. I think the answer choices are:
Log StartFraction 8 Over 25 EndFraction
StartFraction log 8 Over log 25 EndFraction
log StartFraction 25 Over 8 EndFraction
----> StartFraction log 25 Over log 8 EndFraction
So the answer is D
