What is the prefix, symbol, and meaning of the exponent 10 to the 6th power?

Explanation:
In this question the key idea is SI prefixes, which attach to units to indicate large or small powers of ten. The exponent 10^6 corresponds to the prefix mega, abbreviated with the symbol M, and it means one million. That’s why megahertz (MHz) or megawatt (MW) use this prefix. The other options point to different powers: kilo (k) is 10^3, giga (G) is 10^9, and milli (m) is 10^-3. So the match for 10^6 is mega, M, million.
