Which of the following prefixes denotes one million (10⁶)?

• A. Deci
• B. Kilo
• C. Mega
• D. Centi

Answer: (C)

The prefix that denotes one million, or \(10^6\), is "Mega." This prefix is commonly used in various fields, including chemistry and physics, to simplify the representation of large quantities. For instance, a megabyte (MB) is one million bytes, and a megawatt (MW) is one million watts. Using scientific notation and a prefix helps make communication regarding large numbers clearer and more manageable. In contrast to "Mega," the other prefixes mentioned represent different powers of ten: "Deci" denotes \(10^{-1}\) or one-tenth, "Kilo" denotes \(10^3\) or one thousand, and "Centi" denotes \(10^{-2}\) or one-hundredth. Understanding these prefixes is crucial for accurate interpretation of measurements in scientific contexts.
