#)Giải :
Ta có : 1839 > 1639 = 2156 > 2135 = 3227
1839 > 3227 => (-18)39 < (-32)27
Vậy : (-18)39 < (-32)27
#~Will~be~Pens~#
Trả lời :
Ta có: 3227=(25)27=2135<2156=24.39=1639<1839
=>(-32)27>(-18)39
Vậy (-32)27>(-18)39
\(\downarrow\)
Ta có \(32^{27}=\left(2^5\right)^{27}=2^{135}< 2^{136}=\left(2^4\right)^{39}=16^{39}< 18^{39}\)
\(\Rightarrow\left(-32\right)^{27}>\left(-18\right)^{39}\)
\(\text{Bài giải}\)
\(\text{Ta có : }\)
\(32^{27}=\left(2^5\right)^{27}=-2^{135}< 2^{156}=2^{4\cdot39}=16^{39}< 18^{39}\)
\(\Rightarrow\text{ }\left(-32\right)^{27}>\left(-18\right)^{39}\)
