Exponent numeric display.

Hello, I would like to apologize in advance for the somewhat weird english I'm going to write.

The problem is as follows, I need to make a program in javascript that creates a random monomial and then you have to solve it.

My isse is, how can I make the exponent look like the normal small number, for example:

This is how my exercise is shown: -18x2 when x is -54

I want it to show it like this: -18x² when x is -54

Any help would be greatly appreciated.

Code:

-18x2

What I'm trying to use to convert is ("x" + Monomio.grado) where Monomio.grado is my exponent, but using or .sup doesnt appear to change anything.

Sorry for the rather stupid question...

Code:

var str = "-18x"

var exponent = "2";

var x = str + exponent.sup();

document.write(x);

If I use an associative array should it work like this?

(monomial.exponent).sup

I do not have the faintest idea what your question is. But I do not see how associative arrays come into it. :confused:
sup() is an inbuilt Javascript method which is used to display a string as superscript text. My example shows how to apply that to the exponent (i.e. squared).

You can use the split() method to divide a number with exponent into its parts-

Code:

<script type = "text/javascript">



var string = "-18x12";  // minus 18 raised to the power of 12

var ssplit = string.split("x");

var str = ssplit[0] + "x";

var exponent = ssplit[1];

var x = str + exponent.sup();

document.write(x);



</script>

I think he just misused terminology, Philip.

I think he has an object, referenced by the variable monomiial (or maybe Monomio--he uses different names in different posts) and that object has a property named exponent (or maybe grado--again, different names in different posts).

SO I think the answer is "yes".

I think if he simply uses monomial.exponent.sup() (or maybe it is Monomio.grado.sup()??) it will work.

It will not work as he showed it: (monomial.exponent).sup because he omitted the () after sup.
