Answer:

3.96*10⁻¹¹

Explanation:

Scientific notation:

Step 1: Here the powers of 10 are not same. So, adjust the powers of 10 in such a way that they have same index.

3.60 *10⁻¹² = 3.60 * 10⁻¹⁻¹¹

= 3.60*10⁻¹ * 10⁻¹¹

= 0.360 * 10⁻¹¹

3.60*10⁻¹² + 3.60*10⁻¹¹ = 0.36 *10⁻¹¹ + 3.60 * 10⁻¹¹

Step2: Now add the numbers

= ( 0.36 + 3.60)*10⁻¹¹

= 3.96*10⁻¹¹
