How do you write 0.000027 in scientific notation?

Question

2.7 * 10^-4
0.27 * 10^-5
27 * 10 -4
2.7 * 10^-5

Answer 1

To write the number 0.000027 in scientific notation, you move the decimal point to the right until you have a number between 1 and 10.

Here's how it works:

• Move the decimal point 5 places to the right: 2.7
• Since you moved the decimal 5 places to the right, the exponent of 10 will be negative.

Thus, 0.000027 in scientific notation is \(2.7 \times 10^{-5}\).

So the correct answer is: 2.7 * 10^-5.
