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