For an exact power of 2 (1, 2, 4, 8, 16, 32, etc., but also 1/2, 1/4, etc.), you can try out different exponents until you get it right. To write any number (greater than 0) as a power of 2 is equivalent to taking the logarithm of that number in base 2, which is the same (if you call your number "n") as calculating log n / log 2 (using the same base for both logarithms - for example, both in base 10, or both in base e).

∙ 9y agoIf n= the number you want to power 2 by then 2n would be 2 to the power of n
similarly 23 is 2 to the 3rd (8)

How do you write the number 81 as a power in math?
9 to the power of 2 = 81
Who to write Two to the second power times three to the third power?
Its hard to do type it out. Easier to write it. ^ means the number is raised or superscript. X = (2)^2 X (3)^3
How do you write 20 squared?
To write powers of a number you write the number, followed by the number of the power in superscript. For example, a number to the second power is x2, a number to the third power is x3 and so on. Squaring is taking a number to the second power. Thus 20 squared is 202, which equals 400.

How do you write a number to the power of 2 on your keyboard?
102 and then make 2 superscript on the font tab. Or, write 10^2 which is acceptable; you can find ^ as capital 6

How do you do squared after a number?
Write the number 2 in superscript (that is, a small number to the upper right). If you're trying to do it by computer and you don't have the option to use superscript, the standard is to put a caret and then a 2. Here's an example of how to write 5 squared: 5^2 Incidentally, this is the same way you write a number to any other power.
How do you write the number 23 only using the number 2?
(22) + (2/2) = 23 (2 raised to the 22 power) + (2 x 2 x 2) - (2/2) = 23
How do you write a number to the power of 2 on a Hispanic key board?
In Microsoft Word, there is the superscript button in the home tab. It has an A with a little "floating 2" to its right. Press that then enter your text. Or, you can just write (Number)^2. That is widely accepted.
