What does ^ mean?

Question

help please

Answer 1

It means, raised to the power of. Here are some examples:

2^4 = 2*2*2*2

7^3 = 7*7*7

9^1 = 9

1^3 = 1*1*4

Answer 2

^ means to the power of whatever follows.

3^2 is 3 raised to the power of 2 or 3 squared or 3x3

The other answers have explained this well but there are a couple of other points for you to note:

1. We use ^ because that is the symbol used on calculator keys to raise a number to a power. Using the above example you press 3^2 = and 9 is displayed. I guess we use the symbol in these answers because we can't write, for example, the 2 as a superscript - that is writing the 2 to the top right corner after the 3.

2. You can have fractional powers so we would type, for example, 16^1/2 which is 16 raised to the power of a half which is, as I am sure you know, the square root of 16.

3. You can also have negative powers, or indices as the are often called. I find you have to look carefully at the answers for the minus sign. For example 3^4 and 3^-4, the minus sign can easily be missed.

Answer 3

2^3 = 2 x 2 x 2 = 8

Answer 4

in computing maths it means "to the power of"

ie 3^2 = 3 to the power of 2 (or 3 squared)

10^6 = 1 million etc

Answer 5

to the power of, so 3^6, means 3 to the power 6, or 3x3x3x3x3x3

Answer 6

You already have the mathematical explanations so I will
give you a verbal; você gosta de côco?
Trans: do you like coconuts.
^ is a circumflex accent in Portuguese
vôce=you the o would have an open pronunciation but with the
^ it is rounded and hollow and the accent is on the last syllable
and not the first.
côco is a coconut and although the accent is in the correct
place it produces the same round hollow back of throat sound.

Answer 7

we need context!

Since you're in maths, I assume you mean the use of ^ to signify "to the power of", since in typewriter speak you can't superscript easily so the ^ convention was used to get round it. Hence

x^2

means x squared.

I think it originated in FORTRAN where it really does mean "to the power of", as far as I recall.

In other contexts I think I've seen ^ meaning "logical NOT", so ^A would mean 1 if A is 0, and 0 if A is 1

and still again, in rendering non-printing characters, a return character (or is it a line feed?) can come out as ^M

in the real world, ^ on a letter means you pronounce it different.

Answer 8

The Power Of.

Answer 9

it is a symbol used for denoting exponents. For example 2^2 would be 2 to the second power which would be 4.

Answer 10

'^' means 'to the power of'

for example, x^(3/2) means 'the square root of x cubed'

in number terms (4)^(3/2) would mean 'the square root of 4 cubed' ie 'the suare root of (4x4x4) which is the square root of 64 which is 8

alternatively,you could take the square root of 4 which is 2,then cube it ie (2x2x2) which is still 8

i hope that this helps
