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
