Your machine probably just doesn't support the original font, so it produced this other character from whatever font it could provide. Check the course requirements for which font you need to install.

From the context I assume it represents 'the reciprocal of'. So with the implied multiply operator we'd get
13) 4
14) 1 / 3x^2
But what do I know - I'm 65!

Oh, now that's an idea. Thanks.

It may be a good idea but my answers are wrong as I mis-read the two questions. If I'm right about the reciprocals bit then the correct answers I reckon are:
13) c^4 14) 1 / x^6
(I'm happy to sit at the back of the class)

If your kid's been out, how did he get the homework? Did he download it from a webpage or some such? If so, it might be a font mismatch between the teacher's computer and yours.

I have multiple degrees in abstract math (functional analysis mainly) and I have never seen that symbol used in English, German or Russian texts. Must be something new.....

Maybe it's a capital G.

I've asked some maths experts and they've requested more information. Do you have earlier pages in the chapter you could post? So far nobody has seen this symbol used in this way.

Nope, this is just a worksheet we think the teacher downloaded from the 'Net. So it is likely a mis-translation of some sort.
Interestingly, the next day the kid brought home another worksheet and my wife was able to find it -- with the answers. 
We're not impressed by the quality of the "teaching" that goes on now.
|

|
If it's not too much trouble, what were the answers? Was it a multiplication symbol as suspected?
|
|
|
|
|
How old is your kid?
If he/she is primary school pupil then the sign is just a incorrectly rendered multiplication sign.
There is absolutely nothing else you can do with c ^ (12/5) and c ^ (3/5) but to multiply them.
And solutions are
13) c ^ 3
14) x ^ (21/4) (unless part of formula is missing on right)
Or the question was just for laughs ...

It's supposed to be algebra 1, 9th grade. And it's likely supposed to be multiplication.

If you know the name of the book and the page number, then you might be able to find an errata. Most printed text books have pages and pages of errata.
If they do not let you bring the books home, then there is probably an online version with some lame password like schooldistrictname2015. Hopefully, the online version would be fixed but you might still need to find an errata.

Kinda expected. This will be interesting.

It will if the cost of Xamarin comes down to a reasonable level as a result - which I'd imagine it could. That could really boost usage of .NET (ish) into the mobile market which presumably is why MS are buying them in the first place. Either that or to crush them utterly - difficult to tell with MS sometimes...
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

Didn't go very well.
Installed Ubuntu in VMWare player, worked fine.
Downloaded some updates, restarted, works not so fine.
It hanged at startup on "Stopping Restore Sound Card State".
Removed the virtual sound card and it now hangs on "Stopping System V runlevel compatibility".
I guess the same goes for Linux as for Windows, don't install updates

If I had a pound for every year that has been the year of the linux desktop, I could probably buy a few beers.

My first Linux experiences went very well:
- Installed Mint.
- Installed Wine.
To my surprise:
W32 App including SQL Server works perfect.

I'll try Mint next, after I'm done with Debian (which I don't like already and the installer hasn't even finished yet)
|
|
|
|
|
Unfortunately Mint doesn't give me the right screen resolution and it ignores the VMWare Player.
Other than that it seems to work fine.
