2 to the power of negative 3

Since your exponent is negative, you will have to make a fraction. To make the exponent even, you will make #1# the numerator and #2# to the power of #3# the denominator.

Now that you have a fraction, and the exponent is no longer negative, you will keep #1# as the numerator and have #2*2*2# as the denominator.

You can simplify the denominator. #2# times #2# is #4# times #2# again, is #8#. The numerator is #1# and the denominator is #8#, which is the fraction #1/8#.

Also, #1# will always be the numerator when you are trying to simplify a number that has a negative exponent.

2 to the negative 3rd power is conventionally written as 2-3, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 2^-3.

2-3 stands for the mathematical operation exponentiation of two by the power of negative three.

As the exponent is a negative integer, exponentiation means the reciprocal of a repeated multiplication:

2 to the negative 3rd power =

The absolute value of the exponent of the number -3, 3, denotes how many times to multiply the base (2), and the power’s minus sign stands for reciprocal.

Thus, we can answer what is 2 to the negative 3rd power as

2 to the power of minus 3 = 2-3 = 1 / 8.

2 to the Power of -3

Reading all of the above, you already know most about 2 to the power of minus 3, except for its inverse which is discussed a bit further below in this section.

Using the aforementioned search form you can look up many numbers, including, for instance, 2 to the power minus 3, and you will be taken to a result page with relevant posts.

Now, we would like to show you what the inverse operation of 2 to the negative 3rd power, (2-3)−1, is. The inverse is the 1 over the 3rd root of 23, and the math goes as follows:

(2-3)−1
=

=

=

=

Because the index of 3 is not a multiple of 2, which means odd, in contrast to even numbers, the operation produces only one value: (23)−1

.

Make sure to understand that exponentiation is not commutative, which means that 2-3 ≠ -32, and also note that (2-3)-1 ≠ 23, the inverse and reciprocal of 2-3, respectively.

What is 2 to the negative power of 3?

Answer and Explanation: 2 to the negative 3rd power is 1/8, or . 125 in decimal form.

What does to the power of negative 3 mean?

Whereas, the negative exponent tells us how many times we have to divide the base number. In other words, the negative exponent describes how many times we have to multiply the reciprocal of the base. An example of negative exponents is 3-2.

How do you solve 2 to the negative power?

We know that an exponent refers to the number of times a number is multiplied by itself. For example, 32 = 3 × 3. In the case of positive exponents, we easily multiply the number (base) by itself, but in case of negative exponents, we multiply the reciprocal of the number by itself. For example, 3-2 = 1/3 × 1/3.

What does a negative power mean?

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.
