Question

so sánh (-32)^9 và (-16)^3

mn giúp mk nhé, thank trước ạ

Answer 1

(-23)^9 < (-16)^3

Answer 2

(-32)^9<(-16)^3 vì

(-32)^9= ((-2)^5)^9= (-2)^45

(-16)^3= ((-2)^4)^3= (-2)^12

Vì (-2)^45<(-2)^12=> (-32)^9<(-16)^3

Answer 3

\(\left(-32\right)^9=\left(-2^5\right)^9=\left(-2\right)^{45}\)

\(\left(-16\right)^3=\left(-2^4\right)^3=\left(-2\right)^{12}=2^{12}>-2^{45}\)

\(\Rightarrow\left(-16\right)^3>\left(-32\right)^9\)
