Answer; It means power! For example, the fourth power of 50 is the fourth power of 50! ""is a mathematical symbol used to represent three-level operation. When inputting mathematical formulas on the computer, this symbol is often used to represent the power because it is inconvenient to input the power. For example, the fifth power of 2 is usually expressed as 2 5. On some calculators, this symbol is used to represent power. (For the operation of power, see Power) ""is a bitwise logical operator-bitwise exclusive or reversible operator. Only when the two bits compared are different, the result is 1, otherwise the result is 0. Therefore, when calculating, we should first convert the numerical value into binary, compare the bits, and then convert the obtained result into the original binary number. The following example: 3^ 5 =>；; 1 1 ^ 10 1 = 1 10 = >6。 This symbol is usually represented as the "Ctrl" key. When the computer represents a combination key, this symbol is usually represented as the "Ctrl" key. For example, F stands for Ctrl+F, and this symbol also stands for eyes in the symbol of smiling face (_), representing a curved eyebrow.
