Answer:
[tex]1.46\times 10^{10}[/tex] krill.
Step-by-step explanation:
We have been given that an adult blue whale can eat [tex]4.0\times 10^7[/tex] krill in a day. We are asked to find the number of krill an adult whale can eat [tex]3.65\times 10^2[/tex] days.
[tex]\text{Krill eaten in given time}=3.65\times 10^2\cdot 4.0\times 10^7[/tex]
Using exponent property [tex]a^b\cdot a^c=a^{b+c}[/tex], we will get:
[tex]\text{Krill eaten in given time}=3.65\times 4.0\times 10^{7+2}[/tex]
[tex]\text{Krill eaten in given time}=14.6\times 10^{9}[/tex]
[tex]\text{Krill eaten in given time}=1.46\times 10^{10}[/tex]
Therefore, an adult whale can eat [tex]1.46\times 10^{10}[/tex] krill in [tex]3.65\times 10^2[/tex] days.
