2 to the 78th Power

Welcome to 2 to the 78th power, our post about the mathematical operation exponentiation of 2 to the power of 78. If you have been looking for 2 to the seventy-eighth power, or if you have been wondering about 2 exponent 78, then you also have come to the right place. The number 2 is called the base, and the number 78 is called the exponent. In this post we are going to answer the question what is 2 to the 78th power. Keep reading to learn everything about two to the seventy-eighth power.

What is 2 to the 78th Power

2 to the 78th power is conventionally written as 278, with superscript for the exponent, but the notation using the caret symbol ^ can also be seen frequently: 2^78.

278 stands for the mathematical operation exponentiation of two by the power of seventy-eight. As the exponent is a positive integer, exponentiation means a repeated multiplication:

2 to the 78th power = \underbrace{ {\rm 2 \times\thinspace … \times\thinspace 2} }_{\rm 78 \thickspace times}

The exponent of the number 2, 78, also called index or power, denotes how many times to multiply the base (2).

Thus, we can answer what is 2 to the 78th power as

2 to the power of 78 = 278 = 3022 3145490365 7293676544.

2 to the Power of 78

Reading all of the above, you already know most about 2 to the power of 78, 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 78, 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 78th power, (278)−1, is. The inverse is 78th root of 278, and the math goes as follows:

(278)−1
= \sqrt[78]{2^{78}}
= 2^{78/78}
= 2^{1}
= 2

Because the index of 78 is a multiple of 2, which is even, in contrast to odd numbers, the operation produces two results: (278)−1 = \pm 2; the positive value is the principal root.

Make sure to understand that exponentiation is not commutative, which means that 278 ≠ 782, and also note that (278)-1 ≠ 2-78, the inverse and reciprocal of 278, respectively.
