Answer:
1. 6.9×10^6, 2. 3.8×10^1, 3. 8.19×10^-2, 4. 14.175×10^4,5. 0.2375×10^13,6. 3.75×10^-16
Step-by-step explanation:
1.3.9×2.3×10^2×10^4
=6.9×10^6
2.4.18×9×10^4×10^-6
=3.8×10^1
3.9.75×8.4×10^4×10^-6
=8.19×10^-2
4. 9.45/1.5×10^10/10^6
=14.175×10^4
5.1.14/4.8×10^5/10^-8
=0.2375×10^13
6.9/2.5×10^-11/10^4
=3.75×10^-16
