Q means in math
Jun 25, 2014 · Writing {\displaystyle x\in A} x\in A means that "x is an element of A". Equivalent expressions are "x is a member of A", "x belongs to A", "x is in A" and "x lies in A". The expressions "A includes x" and "A contains x" are also used to mean set membership, however some authors use them to mean instead "x is a subset of A". In mathematics, a number written in superscript is used to represent an exponent. In the case of x2, this can be read as "x to the power of two" or simply "x squared". An exponent is a way of noting how many instances of a value should be multiplied by itself. For example, 34 can also be expressed as 3 × 3 × 3 × 3.
