Scientists write that with a superscript and describe it as 'to the power of'.

科学家们用上角书这些数字，并将其描述为 " 次幂" 。

Or if you're looking at it in a book, it might just be a bolded capital R with a 2 superscript like this.

或者，如你在一本书中查看它，它可能只是一个粗的 R 和一个 2 上，就像这样。

And so if we were to talk about a real coordinate space generally, you'll often see the notation Rn, with n as a superscript.

因此， 如我们一般地谈论一个真实的坐，你经常会看到符号 Rn，上面是 n。

It's actually going to make things easier for us if we give a special name to this weighted sum, like z, with the same superscript as the relevant activations.

如我们为这个加权和指定一个特殊的名称（例如 z），并且具有与相关激活相同的上，实际上会让我们的事情变得更容易。

To bring out the ''phonetic'' difference, an aspirated sound is transcribed with a superscript" h" after the symbol of the sound, such as [p, t], so a phonetic transcription for peak is [p'i: k] and that for speak is [spi: k].

英语词典通常把 peak 和 speak 的发音分别转为 /pi： k / 和 /spi： k/，但这两个词的实际发音需要遵循一条规则，即 /p/ 在 /s/ 后面不送气，在其他位置上送气。为了表现这一语音上的差别，送气音在转时要在发音符号后面加上上符号 (如 [ph， th] 等)，于是 peak 的语音转是 [phi： k]，speak 的语音转是 [spi： k]。
