想向各位请教个问题：在数学上，常有“字母＋上下标”，在英语中，遇到上下标怎么发音？比如，A’，Aa,（a是A的下标） 分别怎么读呢？

谢谢大家！

A' is pronounced as "A prime" [praim]

I am not quite sure about the subscript, if it is a number, such as A1 (1 as the subscript), usually you can just say A one.

Most times you just pronouce them literally.

aⁿ  a to the n^th power or  a to the n^th

Ai,j    pronouced as "A i comma j"

The best online dictionary (www.answers.com) with pronounciaton sound icon to click on, 14 language translation, spell checking, a lot of more !!! Go get the American accent!!!
