Exponentiation - Wikipedia
1 month ago - Programming languages generally express exponentiation either as an infix operator or as a function application, as they do not support superscripts. The most common operator symbol for exponentiation is the caret (^). The original version of ASCII included an uparrow symbol (↑), intended ...

Exponent Operator (^) | Caché Basic Reference | Caché & Ensemble 2018.1.4 – 2018.1.12
For details on valid argument values and the value returned for specific combinations of argument values, see Exponentiation Operator in the “Operators and Expressions” chapter of Using Caché ObjectScript. The following example shows valid uses of the exponent operator (^) and the base-10 exponent symbol (E).
The caret ^ symbol means exponentiation informally in math. Why not a symbol for log too?
^ is not really a symbol for exponentiation. It's uses as one because of early limitations of character encoding really. It's supposed to suggest that you put what follows up, which is how exponentiation is written. Now, the real question is why is there a common notation for exponentiation function (ax) but no notation for its inverse function beyond giving the function a name. If I had to guess, it would be because exponentiation is much older. In addition, it's actually rather annoying that we insist on writing all exponentials in that ax way, which is why people often write exp(x) instead when a=e for instance. Writing things as superscripts is really not great notation. For instance, in calculus a common mistake would be to take the derivative of ex as x ex-1. This is because people want to think notationally. More on reddit.com

ℝn×m means n×m matrices with real number entries. so x_k is a matrix/column vector with N_s entries and 1 column. More on reddit.com

November 3, 2023Why is the exponentiation operator ** instead of say ^?
Because ^ is the bitwise xor operator. That symbol has been used in many other languages, and Python uses the same operator (along with ~, &, and | for other bitwise operators). Most of those languages don't have an exponentiatioin operator, so a new operator had to be used in Python when exponentiation was added. More on reddit.com

r/math on Reddit: The caret ^ symbol means exponentiation informally in math. Why not a symbol for log too?
March 6, 2015 -
Plus, minus, multiply, divide, and exponentiation all have symbols in math (+, -, *, /, ^ ) . But why isn't there the missing log symbol too? Here's how it would work:
4 ^ 5 = 1024 (as is standard for exponentiation)
1024 _ 4 = 5 ("_" is the new log operator!)
Look how much more elegant <1> is compared to <2>, <3> or <4>. We shouldn't need to do those hacks to express the same thing:
1: 1024 _ 4 = 5
2: log(1024)/log(4) = 5
3: LogBase(1024,4) = 5
4: The standard math syntax in LaTeX format: [; \sqrt[\leftroot{-2}\uproot{2}\4]{1024}=5 ;]
NB: It doesn't have to be an underscore symbol. It's just the first thing that sprang to mind.

There is a special symbol for the inverse of exponentiation: √. The reason it's not what you want is that exponentiation is fundamentally different from addition and multiplication in that it's not even a little bit commutative. And of the two inverses that you could want to compute, the one with a fixed exponent (x2) is far more common than the one with a fixed base (2x). So that's why it gets a special symbol and the logarithm doesn't.

Exponentiation (**) - JavaScript | MDN
The exponentiation (**) operator returns the result of raising the first operand to the power of the second operand. It is equivalent to Math.pow(), except it also accepts BigInts as operands.

Basic rules for exponentiation - Math Insight
If $n$ is a positive integer, we define \begin{gather} x^{-n} = \frac{1}{\underbrace{x \times x \times \cdots \times x}_{n \text{ times}}}. \end{gather} Then the rule for the quotient of exponentials works even if $a< b$: \begin{align*} \frac{x^a}{x^b} &= \frac{\quad \underbrace{x \times \cdots \times x}_{a \text{ times}}\quad}{\underbrace{x \times \cdots \times x}_{b \text{ times}}}\\[0.2cm] &= \frac{1}{\underbrace{x \times \cdots \times x}_{b-a \text{ times}}}\\[0.2cm] &=x^{a-b}. \end{align*} When $b>a$, the exponent $a-b$ is a negative number.

January 20, 2026 - In mathematics, a power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten ...

Definition of Exponents & Radicals - Math Skills Overview Guide - Library Guides at Davenport University
Exponents - An exponent is the power p in an expression of the form $$a^p$$ The process of performing the operation of raising a base to a given power is known as exponentiation. (where a ≠0) Radicals - The symbol $$\sqrt[n]{x}$$ used to indicate a root is called a radical and is therefore read "x radical n," or "the nth root of x." In the radical symbol, the horizontal line is called the vinculum, the quantity under the vinculum is called the radicand, and the quantity n written to the left is called the index.
