I have this value

N = 10^9 (9 in superscript)

How to read that in English? translating from my native language, I would say

Ten base of nine.

but is that really correct?

  • 2
    Ten to the power of nine. Ten raised to the ninth power. Ten to the ninth power.

1 Answer 1


Formally it is

Ten to the power of nine

but more commonly:

Ten to the nine or Ten to the ninth

The use of Base 9 has a very different meaning.
