Question

define the following: 6.7 × 10⁻⁹ equal to one greater than one less than one

Explanation:

Step1: Recall scientific notation

In scientific notation \(a\times10^{n}\), if \(n\) is negative, we move the decimal point \(|n|\) places to the left. For \(6.7\times10^{-9}\), we move the decimal point 9 places to the left.

Step2: Calculate the value

\(6.7\times10^{-9}=0.0000000067\). Now compare this value with 1. Since \(0.0000000067 < 1\), the number \(6.7\times10^{-9}\) is less than one.

Answer:

less than one
