Question

write the number in scientific notation. thickness of soap bubble: 0.0000001 meter 1 × 10 m

Explanation:

Step1: Recall scientific notation form

Scientific notation is \( a\times10^{n} \), where \( 1\leq|a|\lt10 \) and \( n \) is an integer.
For \( 0.0000001 \), we move the decimal point to the right until we get a number between 1 and 10.

Step2: Determine \( a \) and \( n \)

Moving the decimal point 7 places to the right gives \( a = 1 \), and since we moved it to the right, \( n=-7 \).
So \( 0.0000001 = 1\times10^{-7} \).

Answer:

\( 1\times10^{-7} \)
