A friend of yours is arguing that
$\mathrm{x\u2153}$ should be defined to mean something to do with “fractions, or division, or something.” You say “No, it means _____ instead.” He says “That’s a crazy definition!” Give him a convincing argument
why it should mean what you said it means.

On October 1, I place 3 sheets of paper on the ground. Each day thereafter, I count the number of sheets on the ground, and add that many again. (So if there are 5 sheets, I add 5 more.) After I add my last pile on Halloween (October 31), how many sheets are there total?

A
Give me the answer as a formula.

B
Plug that formula into your calculator to get a number.

C
If one sheet of paper is
$\frac{1}{\text{250}}$ inches thick, how thick is the final pile?

Depreciation
The Web site www.bankrate.com defines
depreciation as “the decline in a car’s value over the course of its useful life” (and also as “something newcar buyers dread”). The site goes on to say:
Let’s start with some basics. Here’s a standard rule of thumb about used cars. A car loses 15 percent to 20 percent of its value each year.
For the purposes of this problem, let’s suppose you buy a new car for exactly $10,000, and it loses only 15% of its value every year.

A
How much is your car worth after the first year?

B
How much is your car worth after the second year?

C
How much is your car worth after the nth year?

D
How much is your car worth after ten years? (This helps you understand why newcar buyers dread depreciation.)

We know that
$(a+b)^{2}$ is not, in general, the same as
$a^{2}+b^{2}$ . But under what circumstances, if any,
are they the same?

what is variations in raman spectra for nanomaterials
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
