So it is Heureka.

I had to think about that one  :))

$$\\99.9\% \;\;of\;\;1000!\\\\
=\frac{999}{1000}*1000!\\\\
=\frac{999}{1000}*1000*999!\\\\
=999*999!\\\\$$

there is nothing to evaluate unless you are given a value for a.     :)

Do you mean $$3a^8$$   ?

There is a squareroot button on the calc.

It looks almost like this.  :)

$${\sqrt{{\mathtt{x}}}}$$

What is 1000!-999!  Its 99.9% of 1000!

= 4.0198487281701667977015873148908e+2567

$${\mathtt{4}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}} = {\mathtt{8}}$$

-40=5x

-40/5=x

-8=x

x=-8

can you give an example ! 

Divide both sides by 5

Our calcuator gives.......1462182999.99948003346

Close enough !!!

A candle is in the shape of a sphere with a diameter of 10 cm. (a) Calculate the volume of the candle

The radius r = 5 cm.  So the volume of the candle is 523.598775598299 cm^3

Too right there mate!

Thanks for that, heureka........there are always things popping up on this calculator that I hadn't been aware of, before......of course......If Melody and I relied on a simple thing like punching a few buttons on the calculator, we wouldn't be able to "show off" as much as we do.....!!!

Thanks Heureka,

I never stop being surprised by what the web2.0 calc can do.  

Thanks for showing us.  

What is 5 m squared converted to cm squared ?

$$\boxed{5\ m^2 = 50000\ cm^2}$$

There are 100cm in a meter. So, 1 square meter would be 1m x 1m =  100cm x 100cm = 10000cm²

So, 5 square meters would be 5 times as much = 50,000cm²

[ To see this more clearly, imagine a suare with a side of √5m. Then the area would be 5m². So, in cm, the side would be 100√5 cm. And (100√5 cm)² = 50,000cm² ]

Well there is 100 cm in a metre

so 

there is 100^2cm^2 in a m^2

10 000cm^2=1m^2

so

50 000cm^2 in 5m^2

Hi all,

Great answers today from Alan, heureka, Geno3141, CPhill, TakahioMarda, Britishrain and LancelotLink.

Thanks all.    

Now for the interest posts:

1) This Physics one looks interesting.  Thanks Alan

We probably don't have enough bananas to satisfy Chimp Ayumu....however....we DO stock quite a quantity of peanuts......as long as she promises not to get any  (spherical) shells on the floor......

1) Rosala is back in Camelot  Yeah!

Hay, wait just a minute . . .

That might have been true until I (we) joined the forum.

This might take me a few _(dozen) hours to figure out. Maybe only a couple of hours if we chimps brainstorm.

If we really get in a pinch, Chimp Ayumu is skilled in high-level maths, and she helps us sometimes.

                                  Chimp Ayumu

I like her, but some of the board members don’t because she makes us look kind of dumb.

We really need a fulltime, high-level mathematician, but she won’t join our board. She says we couldn’t grow enough bananas to get her to join.

We know how to count bananas, though.

It's math....it's supposed to look hard......if it looked easy.......the questioners would be on to us!!!!! LOL!!!

Chris is of course correct.  He just makes it look hard LOL

1000!=999!x1000

so

1000!-999!

= 999!x1000 - 999!x1

          I can factor out the 999!

=999!(1000-1)

=999! x 999

Notice that

n! - (n -1 ) !   =

[n x (n-1) x (n-2) x.......x 3 x 2 x 1 ]  - [ (n-1) x (n-2) x.......x 3 x 2 x 1 ]

And factoring out the common term, we have

[ (n-1) x (n-2) x.......x 3 x 2 x 1 ] [n  - 1]  =

[n-1]! * [n-1]

So....... 1000! - 999! =

999! * (999)       ......whatever that is !!!  (it's huge, to be sure)
