Answer 2

Answer:

$1.) \: \: 12 {5}^{ \frac{1}{3} } \\ = (5 \times 5 \times 5 {)}^{ \frac{1}{3} } \\ = {5}^{3 \times \frac{1}{3} } \\ = {5}^{1} \\ = 5$

$2.) \: p(t) = 2 +t + 2 {t \: }^{2} - {t}^{3} \\ = - {t}^{3} + 2 {t}^{2} + t + 2 \\ p(0) = ( - 0 {)}^{3} + 2 \times (0 {)}^{2} + 0 + 2 \\ = - 0 + 0 + 2 \\ = 2 \\ p(1) = ( - 1 {)}^{3} + 2 \times ( 1 {)}^{2} + 1 + 2 \\ = - 1 + 2 + 3 \\ = 1 + 3 \\ = 4$

I hope it will help you
