Express the answer in scientific notation and with the correct number of significant figures: (6.32 x 10-4) ÷ 12.64

The correct answer is: 5 * 10 ^ -5

Explanation:

Hello! Let's solve this!

To write a number in scientific notation, we have to grab, from the number to convert, the numbers that are between 0 and 9. Then we will count the places that we moved the point. If we move it to the left, the exponent of 10 is positive.

If, on the contrary, we move the point to the right, the exponent of 10 is a negative number.

In this case, the operation to be performed is: (6.32 x 10-4) ÷ 12.64 = 5 * 10 ^ -5

We conclude that the correct answer is: 5 * 10 ^ -5

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
