Какое из данных чисел принадлежит промежутку \( [5 ; 6] ? \) \( \begin{array}{llll}\text { 1) } \sqrt{5} & \text { 2) } \sqrt{6} & \text { 3) } \sqrt{28} & \text { 4) } \sqrt{41} \\ \text { Ответ: } \square & & \end{array} \)

1. Choose the correct answer from the given ones : \( \begin{array}{llll}\text { 1 If } X=\{2\}, Y=\{3,4\} \text {, then } n\left(X^{2}\right) \times \mathrm{n}(\mathrm{Y})=\ldots \ldots \ldots \ldots \\ \begin{array}{llll}\text { (a) } 1 & \text { (b) } 2 & \text { (c) } 3 & \text { (d) } 4\end{array}\end{array} \).

A population of 60 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 600 deer. Absent constraints, the population would grow by \( 10 \% \) per year. Estimate the population after one year \( p_{1}= \) Estimate the population after two years \( p_{2}= \)

\[ S_{n}=1+2+3+\cdots+n \] Calcule \( S_{278} \)

\( \frac{21}{35}=\frac{}{100} \)

Expand the logarithm fully using the properties of logs. Express the final answer in terms of \( \log x \). \[ \log 8 x^{3} \] Answer Attempt 1 out of 2
