I have to write x/100000 with square character: x*105 ,but the '5' should be above 10 so it is known that it is x/10/10/10/10/10.
How do I do that?

If you are trying to get x*10^{5}, as you would write it by hand, then your only option is your word processor's superscript option for text (unless you have a full equation editor feature handy). The only superscript characters I know of in Unicode are 1, 2, 3 (listed as sup1, sup2 and sup3 respectively in this reference) and those characters that are naturally above the centreline (such as the degree symbol). The common way of representing such a math clause in plain text is 


Assuming you mean in a word processor of some sort, you probably want to format the '5' as superscript. Also, if it's '5', then is isn't a square character. It's only squaring when it's raised to the power of two. 


You can copypaste superscript numbers (and minus sign) from here: ⁻ ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ These can also be helpful: ½ ⅓ ⅔ ⅕ ⅖ ⅗ ¼ ¾ ⅘ ⅙ ⅚ ⅛ ⅜ ⅝ ⅞ 

The most common superscripts of 1, 2 and 3 were included in ISO88591, but a full superscript number set is available in Unicode. U+2075 is ⁵. Details are available from http://www.unicode.org/charts/PDF/U2070.pdf, which is authoritative. More information is also at Wikipedia. 


If you are on a Mac, type Ctrl+Cmd+Space and you will get an Emoji popup. Then, type the number you want (2) and the square will be part of the results 😎
