MathML Superscripts

MathML superscript is created with the <msup> tag. You have to place the base inside the <msup> tag, followed by the superscript.

Example

If you want to write x², use the following MathML code:

Equivalent MathML code:

MathML element <msup> acts more like a function than a normal HTML markup tag. In the above MathML code, the base and the superscript can be thought of as two “arguments” passed to the <msup> “function.” Both arguments need to be a single MathML element (e.g., <mi> or <mn>). It is fine for working with atomic values like x and 2, but things get more complicated once we start working with compound expressions.

Grouping Sub-Expressions

Group of sub expression is used to include more than one element. It cannot be passed directly into <msup>. Instead, you will have to use <mrow> tag to group the expression, as shown below.

For example: If you want to write e^2x+1, use the following MathML code:

Equivalent MathML code:

It will display the expression like this:

To create a complex base expression, you have to wrap the superscript argument in an <mrow> element.

For example: If you want to write an expression (5x ? 3y)2, use the following MathML code:

Equivalent MathMl code:
