Answer:

3.96*10⁻¹¹

Step-by-step 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
