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).

When you write a squared number is the power 2 3 or 4?
2
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 18 in index form?
To write 18 in index form, you would express it as a power of a base number. In this case, 18 can be written as 2^1 x 3^2, where 2 is the base number raised to the power of 1, and 3 is the base number raised to the power of 2. This is because 18 is equal to 2 x 3 x 3, which simplifies to 2^1 x 3^2 in index form.
How do you write the number 81 as a power in math?
9 to the power of 2 = 81
How can you write 2 to the 4th power in number form?
2 x 2 x 2 x 2 = 16
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 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 5.82 x 10 to the second power in number form?
5.82 times 10^2 in number form is 582.
How do you write the number 81 as a power?
9 to the second power :))
What is index form?
Index form is where a number is expressed using exponents - one number to the power of another. For example, 2 x 2 x 2 x 2 x 2 is the same as 2 to the power of 5, written as 2^5. If you square a number, you write a small 2 above the number, and that is (the number)x(the number). So, it is there twice. If it was 2 x 2 x 2 x 2 x 2 there are five twos in the product, so it's 2 to the power of 5.
How do you write of a to the power of 2?
As a to the power of 2 is the same as a squared then how about this a2
How do you write the number 54 as a power?
you could write it as 233*3
How do you write 12xy to the 2nd power as a product of its factors?
To square a number or an entire segment with variables, parenthesize the particular section and write a square power outside. In this case, it is (12xy)^2. In expanded form, it is 144 . x^2 . y^2 .
How do you convert number 3 to a binary?
You write the number as a sum of decreasing powers of 2. Then for each power, you write 1 if it is present in the sum and 0 if not.So, 3 = 2 + 1 = 2^1 + 2^0and so the binary for 3 (in decimal) is 11.
Is to the power of n the biggest number you can write?
No. There is no number you can write that someone else can't come along and write "plus one" after it.
