Answer:
![3.5\times10^-^1^2](https://tex.z-dn.net/?f=3.5%5Ctimes10%5E-%5E1%5E2)
Step-by-step explanation:
![(7 \times 10^-5) \times (5 \times 10^-8)](https://tex.z-dn.net/?f=%287%20%5Ctimes%2010%5E-5%29%20%5Ctimes%20%285%20%5Ctimes%2010%5E-8%29)
Evaluate
![(7 \times 5)\times(10^-^5\times10^-^8)](https://tex.z-dn.net/?f=%287%20%5Ctimes%205%29%5Ctimes%2810%5E-%5E5%5Ctimes10%5E-%5E8%29)
![35\times10^-^5^-^8](https://tex.z-dn.net/?f=35%5Ctimes10%5E-%5E5%5E-%5E8)
![35\times10^-^1^3](https://tex.z-dn.net/?f=35%5Ctimes10%5E-%5E1%5E3)
![35\times10^1\times10^-^1^3](https://tex.z-dn.net/?f=35%5Ctimes10%5E1%5Ctimes10%5E-%5E1%5E3)
![3.5\times10^1^-^1^3](https://tex.z-dn.net/?f=3.5%5Ctimes10%5E1%5E-%5E1%5E3)
![3.5\times10^-^1^2](https://tex.z-dn.net/?f=3.5%5Ctimes10%5E-%5E1%5E2)
Thus, the answer is ![3.5\times10^-^1^2](https://tex.z-dn.net/?f=3.5%5Ctimes10%5E-%5E1%5E2)
