what is this ^ (sign meaning)?

Question

^
i keep seeing that sign in the maths thing on here and i want to know what it means. i feel stupid .

Answer 1

^ is a sign of exponentiation. 3^2 = 9, for example.

Answer 2

that is the exponent or power



3^2 = 3 * 3 = 9



10^4 = 10 * 10 * 10 * 10 = 10000

Answer 3

The exponent.

What's 3^2?

3*3=9, it's 9.

Got it?

Answer 4

In many computer programming languages, it's a power sign. So 2^3 is two cubed. Because standard keyboards in the past only did ASCII.

Nowadays, if you know how to get special symbols, you can write superscripts and degree symbols in UTF-8, but people like me still put 2^3 because it works in Perl, or C etc.

and I can paste an answer right from "bc" command-line calculator.

Another one is 2**3 which works in FORTRAN

Also sqrt(2) for the square root of two, because we can't find the square root symbol, and

asin(), acos(), atan() for arcsine, arccosine and arctangent (or sin^-1) etc.

Answer 5

The caret (^) usually represents something raised to a power.



For example, 2^3 = 2 raised to the third = 2 cubed = 8.



Hope this helps.

Answer 6

To the power of. Exponential.

1^1 = 1 and 2^2 = 4...

Answer 7

It shows the exponent. Like x^4 would be x multiplied by itself 4 times.

Answer 8

"to the power of"



5 squared = 5^2

Answer 9

it indicates that the number following it is an exponent
