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
