Question

885.5 million miles in scientific notation

Answer 1

To express 885.5 million miles in scientific notation, we first convert million to its numerical equivalent:

1 million = \(10^6\)

So, 885.5 million miles is:

\(885.5 \times 10^6\) miles.

Now we can express 885.5 in scientific notation.

\(885.5\) can be written as \(8.855 \times 10^2\).

Therefore, we combine the two parts:

\[
885.5 \times 10^6 = 8.855 \times 10^2 \times 10^6
\]

Using the property of exponents that allows us to add exponents when multiplying like bases:

\[
8.855 \times 10^{2+6} = 8.855 \times 10^8
\]

Thus, 885.5 million miles in scientific notation is:

\[
8.855 \times 10^8 \text{ miles}
\]
