A tissue can be 0.000075 meters thick.

Setler [38]

Answer:

The required expression is $7.5\times 10^5$

Step-by-step 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. $7.5\times 10^5$

Hence, the required expression is $7.5\times 10^5$
