Answer:

3.0 · 10^10

Step-by-step explanation:

Step 1:  multiply 3.4 and 8.8, obtaining 29.92.  In scientific notation that would be 2.992·10^1.

Step 2:  multiply 10³ and 10^6; that comes out to 10^9.

Step 3:  simplify the product 2.992·10^1 · 10^9:  that's 2.992 · 10^10.  More realistically, that would be 3.0 · 10^10
