- The "2" is actually called the exponent, the x or whatever number is called the base, and
這個 "2 "其實叫指數，x或什麼數字叫基數，而
- So, the whole thing is the "exponent", "base", and "power".
所以，整個就是 "指數"、"基數"、"動力"。

- This is a useful property, because if we have e to the i theta and we want to add some angle phi to it, all we do is just multiply by e to the i times phi, and use the standard exponent rules to rewrite this as a single exponential with the exponents added.
這是一個非常有用的性質，因為如果我們有 e 到 i 的 theta，並想在其上添加某個角度 phi，我們只需用 e 到 i 乘以 phi，然後使用標準指數規則將其改寫為添加了指數的單指數。
- This also means we can pull the phase phi out using exponent rules, and write it as a multiplicative factor, e to the i phi.
這也意味著我們可以利用指數規則得出相位 phi，並將其寫成乘法因子 e 到 i phi。

- I add two numbers in the exponent, say 2³ plus 5, this can be broken down as the product of 2³ times 2⁵.
我在指數中加上兩個數字，比如 2³ 加上 5，這可以分解為 2³ 乘以 2⁵ 的乘積。
