Answer:
[tex]-12*10^9[/tex]
Step-by-step explanation:
[tex](-3*10^3)*(4*10^6)[/tex]
Open up the parentheses
[tex]=-3*10^3*4*10^6[/tex]
Multiply -3 and 4
[tex]=-3*4*10^3*10^6\\=-12*10^3*10^6[/tex]
When multiplying two powers with the same base (10), add the exponents
[tex]= -12*10^(^3^+^6^)\\= -12*10^9[/tex]
I hope this helps!
