La cantidad de un material radiactivo disminuye a la mitad cada 10 años. Si comenzamos con 80 gramos, ¿cuánto quedará después de 30 años?

\[ S_{n}=1^{3}+2^{3}+3^{3}+\cdots+n^{3} \] Calcule \[ S_{35} \]

What is \( \sqrt[3]{27} ? \) \( \square \)

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

A population of 30 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 \( 60 \% \) per year. Estimate the population after one year \( p_{1}=\square \) Estimate the population after two years \( p_{2}=\square \) Question Help: D Post to forum

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