Question

type the correct answer in the box. use numbers instead of words. what is $9.1 \times 10^{-4}$ written in standard form?

Explanation:

Step1: Recall the meaning of \(10^{-4}\)

\(10^{-4}\) means \(\frac{1}{10^4}\), and \(10^4 = 10000\), so \(10^{-4}=\frac{1}{10000}=0.0001\).

Step2: Multiply 9.1 by \(10^{-4}\)

We need to calculate \(9.1\times10^{-4}\), which is \(9.1\times0.0001\). When we multiply a number by \(0.0001\), we move the decimal point four places to the left. For 9.1, moving the decimal point four places to the left gives 0.00091.

Answer:

0.00091
