Question

how do you write $4.976 \times 10^{-4}$ in standard form?

Explanation:

Step1: Recall the rule for negative exponents

For a number in scientific notation \(a\times10^{-n}\), we move the decimal point \(n\) places to the left. Here, \(a = 4.976\) and \(n=4\).

Step2: Move the decimal point

Start with \(4.976\). Moving the decimal point 4 places to the left: first, we have \(0.4976\) (1 place), \(0.04976\) (2 places), \(0.004976\) (3 places), \(0.0004976\) (4 places).

Answer:

\(0.0004976\)
