Question

what is $7.0 \times 10^{-6}$ in standard form?
.0007
.0000007
.000007
.00007

Explanation:

Step1: Recall scientific notation to standard form

For a number in the form \( a\times10^{-n} \), we move the decimal point \( n \) places to the left. Here, \( a = 7.0 \) and \( n=6 \).

Step2: Move the decimal point

Starting from 7.0, moving the decimal point 6 places to the left: \( 7.0\times10^{-6}=0.000007 \)

Answer:

.000007
