Expressing numbers in scientific notation

Question

I assume that scientific discussion in Chinese uses scientific notation, such as 5×10¹². How would I read such a number aloud?

I looked at the rules for saying numbers, as well as the Wikipedia page it links to. The closest thing I could find were the large numbers and metric prefixes.

If I follow the large numbers, then I would guess 五兆, but I'm hoping there's a more general phrase like the way we say, "five times ten to the twelfth power" in English. I found that 乘幂 means exponentiation, so can I say 五倍十二乘幂的十?

Answer 1

五 乘以 十的 十二次冪 Five times 10 to the 12.

Answer 2

OR "五乘以十的十二次方"

(Chinese StackExchange complained "Body must be at least 30 characters; you entered 14" Hence this useless filler...)
