The exponent key is typically located near the top of your keyboard, usually above the number 8 key and sometimes above the letter P key. It is typically labelled as ‘^’ or ‘exp’. To use it, simply press and hold the ‘Shift’ key and press the ‘^’ or ‘exp’ key at the same time. This will allow you to type exponents (such as 2^3 for 2 to the power of 3).
