A plant cell has a length of 0.000085 meters. Which is this length written in scientific notation?
To express the length of the plant cell in scientific notation, we need to write the number as a decimal between 1 and 10 multiplied by an appropriate power of 10.
First, we rewrite the length in standard decimal notation: 0.000085.
Next, we count the number of places we need to move the decimal point to the right to obtain a number between 1 and 10. In this case, we need to move the decimal point 5 places to the right.
Since we are moving the decimal point to the right, the power of 10 will be negative. Therefore, the power of 10 will be -5.
Finally, we can express the length of the plant cell in scientific notation as 8.5 x 10^-5 meters.
To write the length of the plant cell in scientific notation, we need to express it as a number between 1 and 10 multiplied by a power of 10.
The given length is 0.000085 meters. To convert this to scientific notation, we move the decimal point 5 places to the right to obtain 8.5. We then have:
0.000085 = 8.5 × 10^(-5)
So, the length of the plant cell in scientific notation is 8.5 × 10^(-5) meters.
