Question

exercitiul 3 va rog mult dau coroana

Answer 1

Explicație pas cu pas:

$a = {( - 3)}^{ {5}^{2} } \div 3 = {( - 3)}^{25} \div 3 \\ = { - 3}^{25} \div 3 = { - 3}^{25 - 1} = { - 3}^{24}$

$= > a = - {3}^{24}$

$b = {2}^{ {7}^{2} } \div ( - 8)\div ( {2}^{2} )^{5} = - {2}^{49} \div {2}^{3} \div {2}^{10} = - {2}^{49 - 3}\div {2}^{10} = - {2}^{46}\div {2}^{10} = - {2}^{46 - 10} = - {2}^{36}$

$= > b = - ( {2}^{2} )^{24} = - {4}^{24}$

$- {3}^{24} > - {4}^{24} < = > a > b$

=>

$- a > b$
