Question

Express this number in scientific notation.
\[245{,}600{,}000{,}000\]

Answer 1

To express the number \(245{,}600{,}000{,}000\) in scientific notation, we first move the decimal point so that there is only one non-zero digit to the left of it.

Starting with \(245{,}600{,}000{,}000\), we can rewrite it as:

\[
2.456 \text{ (moving the decimal point 11 places to the left)}
\]

Next, we need to multiply by \(10\) raised to the power of the number of places we moved the decimal point. Since we moved it 11 places to the left, we have:

\[
245{,}600{,}000{,}000 = 2.456 \times 10^{11}
\]

Thus, the number \(245{,}600{,}000{,}000\) in scientific notation is:

\[
\boxed{2.456 \times 10^{11}}
\]
