Answer:
3.46 x [tex]10^{10}[/tex]
Step-by-step explanation:
Number of cows 6.4 million = 6.4 x [tex]10^{6}[/tex]
production rate for each cow per year = 5400 = 5.4 x 10³
Total amount of milk produced per year,
= 6.4 x [tex]10^{6}[/tex] x 5.4 x 10³
= (6.4) (5.4) x [tex]10^{6+3}[/tex]
= 34.56 x [tex]10^{9}[/tex]
= 3.46 x [tex]10^{10}[/tex]
