How do you write 4.9 × 105 in standard form

To write \( 4.9 \times 10^5 \) in standard form, you need to move the decimal point in the number \( 4.9 \) five places to the right because the exponent is positive.

Here's how you do it:

1. Start with \( 4.9 \).
2. Move the decimal point 5 places to the right: 

\[
4.9 \times 10^5 = 490000
\]

So, \( 4.9 \times 10^5 \) in standard form is **490,000**.
