Answer:
[tex]9*10^{11}[/tex]
Step-by-step explanation:
we have
[tex](3*10^{6})*(3*10^{5})[/tex]
we know that
[tex](a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)}[/tex] -----> the bases are multiplied and the exponents are added up
so
in this problem
[tex](3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}[/tex]
[tex]=9*10^{11}[/tex]
