Question

Divide: 2.1×10−27×101. enter your answer as an integer or a decimal.

Answer 1

`\(2.1 * 10^(-27) / 10^1 = 2.1 * 10^(-28)\)`

Step-by-step explanation:

To divide
`\(2.1 * 10^(-27)\) by \(10^1\),` subtract the exponents: 2.1 - 1 = 1.1, and the result is
`\(2.1 * 10^(-28)\)`. When dividing numbers with the same base, subtracting the exponents simplifies the expression.

Understanding exponent rules, especially when dividing or multiplying numbers in scientific notation, helps in performing operations efficiently and accurately.

Exploring the rules of exponents, including those related to scientific notation, is fundamental in mathematics and science, providing a systematic approach for handling numbers in various contexts.
