Answer 1

The required expression is
`7.5* 10^5`

Explanation:

Consider the provided information.

A tissue can be 0.000075 meters thick and we need to represent it into scientific notation.

Steps to write a number in scientific notation.

• Move the decimal place to the right so that the new number from 1 up to 10.

• Determine the exponent, the exponent is the number of times you moved the decimal.

Now, consider the number 0.000075

Move the decimal point to 5 place right so that the new number from 1 up to 10.

Now, put the exponent the number of times you moved decimal.
`7.5* 10^5`

Hence, the required expression is
`7.5* 10^5`
