In scientific notation, a number is written as the ______ of a factor and the power of ____, where the factor is a number greater than or equal to $1$ and less than $10$.

• A. sum, $100$
• B. product, $10$
• C. sum, $10$
• D. product, $100$

Answer 1

The correct option is B product, $10$

Detailed step-by-step solution:

• When a number is written in scientific notation, it is written as the product of a factor and the power of $10$, where the factor is a number greater than or equal to $1$ and less than $10$. Or
• $a\times {10}^n$ is said to be in scientific notation if $1\le a<10$, and the exponent n is a positive or negative integer.
• For example,. $9.3\times {10}^3,1\le 9.3<10\text{and}3$ is a positive integer.
