How do you write 8.6 × 105 in standard form?

Answer 1

The expression \( 8.6 \times 10^5 \) is already in standard form. In standard form (also known as scientific notation), a number is expressed as the product of a number between 1 and 10 and a power of 10.

To write \( 8.6 \times 10^5 \) in standard decimal form, you can do the following:

1. Move the decimal point in 8.6 five places to the right (since the exponent of 10 is 5).
2. This gives you \( 860000 \).

So, \( 8.6 \times 10^5 \) in decimal (standard) form is:

860000.
