Answer:
[tex]3.5\times10^-^1^2[/tex]
Step-by-step explanation:
[tex](7 \times 10^-5) \times (5 \times 10^-8)[/tex]
Evaluate
[tex](7 \times 5)\times(10^-^5\times10^-^8)[/tex]
[tex]35\times10^-^5^-^8[/tex]
[tex]35\times10^-^1^3[/tex]
[tex]35\times10^1\times10^-^1^3[/tex]
[tex]3.5\times10^1^-^1^3[/tex]
[tex]3.5\times10^-^1^2[/tex]
Thus, the answer is [tex]3.5\times10^-^1^2[/tex]
