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

On some calculators, this symbol is used to represent power. ' is a bitwise logical operator, and bitwise OR (Xor) is a reversible operator. Only when the two compared bits are different, the result is 1, otherwise the result is 0.

Brief introduction of power supply:

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, negative power, fractional power, irrational power and even imaginary power.

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.

When m is a positive integer, n m represents n times of m in the formula. When m is a decimal, m can be written as a/b (where a and b are integers), n m means n a and b times the root sign. When m is an imaginary number, Euler formula eiθ? = cosθ+isθ, and then solve it by logarithmic property.
