Quote:How to read mc^5 then? em cee what?
em cee to the fifth
em cee to the fifth power
em cee raised to the fifth power
Note: 2nd and 3rd powers have common names: ^2 is "squared" and ^3 is "cubed". Above 3 the power of a number is spoken as a number followed by "raised to the" (or just "to the") followed by the power expressed as an ordinal number and sometimes the word "power":
number [raised] to the nth [power]
e.g. 3^27 is commonly spoken as "three to the twenty seventh".
