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!
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!
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!
