Verified Answer :

10^9 giga, 10^6 mega, 10^3 kilo, 10^-3 milli, 10^-6 micro, 10^-9 nano, 10^-12 pico
Potentially they might want centi which is 10^-2

Answer:

Giga (\(10^{9}\)), Mega (\(10^{6}\)), Kilo (\(10^{3}\)), centi (\(10^{-2}\)), milli (\(10^{-3}\)), micro (\(10^{-6}\)), nano (\(10^{-9}\)),

Explanation:

The prefixes to be known is dependent on your level, either a high school, College or at University. Because some other prefixes not listed above are also important to be known, like; Tera (\(10^{12}\)), femto (\(10^{-15}\)), pico (\(10^{-12}\)). But in general, the stated prefixes required to be known with their applications and symbols.
