Short Answer

Expert verified

None of the above number is less than zero.

Step by step solution

Step 1. Check.

Check whether $1.03 \times 10^{- 21}$ is less than zero or not.

$1.03 \times 10^{- 21}$ can be written as $1.03 \times \frac{1}{10^{21}}$ . This number is smaller in quantity but not less than zero.

Step 2. Check.

Check whether $7.5 \times 10^{2}$ is less than zero or not.

$7.5 \times 10^{2}$ can be written in standard form as 750. Therefore, this number is greater than zero.

Step 3. Check.

Check whether $8.21543 \times 10^{10}$ is less than zero or not.

$8.21543 \times 10^{10}$ is very big quantity therefore, it is greater than zero.

Step 4. Write the conclusion.

As all the three numbers are greater than zero, option J is the required answer.
