A calculator displays 7.85E5. How do you write 7.85E5 in standard form?

Answer 1

To write \( 7.85E5 \) in standard form, you need to understand that \( E \) represents "times ten to the power of." Therefore, \( 7.85E5 \) is the same as \( 7.85 \times 10^5 \).

Now, \( 10^5 \) means \( 10 \) multiplied by itself \( 5 \) times, which equals \( 100000 \).

So, \( 7.85 \times 10^5 = 7.85 \times 100000 = 785000 \).

Thus, in standard form, \( 7.85E5 \) is written as \( 785000 \).
