0.9 to the 365th power = 0.9 365 =1.9845581627 25615283155185926434e-17.

The most basic definition of power is: let a be a certain number, n be a positive integer, and the n power of a is expressed as a? That represents the result of n times multiplication, such as 2? =2×2×2×2= 16。 The definition of power can also be extended to zero power and negative power and so on.

When inputting mathematical formulas on the computer, because it is inconvenient to input the power, the symbol ""is often used to represent the power. For example, the fifth power of 2 is usually expressed as 2 5.

In particular, any positive multiple of 0 is 0, for example: 0? = 0×0×0×0 = 0, and the power of 0 is meaningless.

Extended data:

A brief introduction to the power of negative numbers:

The negative power of 5 can be obtained by dividing 5 by the 0 th power of 5.

For example, the 0 th power of 5 is 1 (the 0 th power of any non-zero number is equal to 1. )

The-1 power of 5 is 0.2 1÷ 5 =0.2.

The -2 power of 5 is 0.04 0.2÷5 =0.04.

Because the-1 power of 5 is 0.2, the -2 power of 5 can also be expressed as 0.2×0.2=0.04.

The -3 power of 5 is 0.2×0.2×0.2=0.008.

It can be seen that the -n power of a non-zero number = the n power of the reciprocal of this number.

Secondly, there are two algorithms for power:

The first is to calculate directly by multiplication, such as: 3? =3×3×3×3=8 1

The second is the multiplication of numbers under the power class, such as: 3? =9×9=8 1
