A number in scientific notation form with a positive exponent has a value __________.

A number in scientific notation form with a positive exponent has a value __________.

• A. Greater than 1
• B. Between 0 and 1
• C. Greater than 10
• D. Equal to 10

Answer: (C)

In scientific notation you write a number as a × 10^n, where the coefficient a is at least 1 but less than 10, and the exponent n is a positive integer. When n is positive, you’re multiplying by a power of ten (10, 100, 1000, etc.), which makes the overall value grow well beyond 1. Since the coefficient is at least 1 and the multiplier is at least 10, the product ends up exceeding 10. That’s why this form is described as having a value greater than 10.
