Answer

<p> <br />1. 4080<br />2. 4284<br /></p>

Explain

<p> <br />1. To find the elephant's mass after one month, we calculate the increase in mass by multiplying the initial mass by 2%. This gives us \(4000 \times 0.02 = 80\) kg. Adding this to the initial mass, we get \(4000 + 80 = 4080\) kg.<br />2. To find the elephant's mass after two months, we first use the mass after one month (4080 kg) and calculate the increase in mass by multiplying it by 5%. This gives us \(4080 \times 0.05 = 204\) kg. Adding this to the mass after one month, we get \(4080 + 204 = 4284\) kg.<br /></p>
