Question

Номер 10 и 11 !!!!!!!!!!!

Answer 1

$- {x}^{5} - x^{2} + 5x^{7} - 8x^{10} \ = - ( - 1 {)}^{5} - ( - 1)^{2} + 5. { (- 1)}^{7} - 8. {( - 1)}^{10} \= - - 1 - 1 - 1.5 - 1.8 \ = + 1 - 1 - 5 - 8 \ = - 13$

$frac{ {2}^{14} . {5}^{6} . (dfrac{5}{10} ) ^{13} }{ {5}^{4} } \ = {2}^{14} . {5}^{2} . (frac{1}{2} ) ^{13} = \ = {2}^{14} . {5}^{2} . ( {2}^{ - 1} ) ^{13} \ = {2}^{14 - 13} .25 \ = 2.25 \ = 50$
