Question

7x10^-9

Answers

GPT-4o mini
The expression \( 7 \times 10^{-9} \) is a representation of a number in scientific notation. It can be interpreted as:

\[
7 \times 10^{-9} = 0.000000007
\]

This means that the number is equal to 7 billionths, or 7 nanometers in some contexts (like measurements in nanotechnology or physics). If you have any specific questions or need further clarification about this number, feel free to ask!
In standard form
GPT-4o mini
The number \( 7 \times 10^{-9} \) is already in scientific notation. If you want to convert it to standard decimal form, it is written as:

\[
0.000000007
\]

This represents the same value expressed with decimal points instead of in scientific notation. If you meant a different context for "standard form," please clarify!
U sure

Yes, I am sure. The expression \( 7 \times 10^{-9} \) in scientific notation means that you take the number 7 and multiply it by \( 10^{-9} \), which is the same as moving the decimal point 9 places to the left.

So, \( 7 \times 10^{-9} \) becomes:

\[
0.000000007
\]

This is indeed the correct standard decimal form for that number. If you have any other questions or need further clarification, please let me know!
