Ta có: \(32^{27}=\left(2^5\right)^{27}=2^{135}\)

\(16^{39}=\left(2^4\right)^{39}=2^{156}\)

mà \(2^{135}< 2^{156}\)

nên \(32^{27}< 16^{39}\)

mà \(16^{39}< 18^{39}\)

nên \(32^{27}< 18^{39}\)

\(\Leftrightarrow-32^{27}>-18^{39}\)

\(\Leftrightarrow\left(-32\right)^{27}>\left(-18\right)^{39}\)

mik biết nhưng ko nói

hồ trần nhi nói rứa thì coi như ko biết còn gì nữa

giải đi mà mấy bạn

   đúng tick nha!!!!

32⁹ = (2⁵)⁹ = 2⁴⁵ < 2⁵² = (2⁴)¹³=16¹³<18¹³

=> (-32)⁹ > (-18)¹³

a, Có : (1/60)^200 = [(1/2)^4]^200 = (1/2)^800

Vì 0 < 1/2 < 1 nên (1/2)^800 > (1/2)^1000

=> (1/16)^200 > (1/2)^1000

Tk mk nha

a) \(\left(\frac{1}{16}\right)^{200}=\left(\frac{1}{2}\right)^{800}< \left(\frac{1}{2}\right)^{1000}\)

a) \(\left(\frac{1}{16}\right)^{200}=\frac{1}{16^{200}}\)

\(\left(\frac{1}{2}\right)^{1000}=\frac{1}{2^{1000}}\)

có : \(16^{200}=\left(2^4\right)^{200}=2^{800}\)

ta thấy \(2^{800}< 2^{1000}\)

\(\Rightarrow16^{200}< 2^{1000}\)

\(\Rightarrow\frac{1}{16^{200}}>\frac{1}{2^{1000}}\)

\(\Rightarrow\left(\frac{1}{16}\right)^{200}>\left(\frac{1}{2}\right)^{100}\)

d, ta có :(-32)⁹=-(32⁹) ;(-18)¹³=-(18¹³)

32⁹=32\(\times\)32⁸=32\(\times\)(32²)⁴=32\(\times\)1024⁴=32\(\times\)1024\(\times\)1024³

18¹³=18\(\times\)18¹²=18\(\times\)(18³)⁴=18\(\times\)5832⁴=18\(\times\)5832\(\times\)5832³

18\(\times\)5832 >16\(\times\)5832=32\(\times\)2916>32\(\times\)1024 =5832³>1024³ 

nên 18¹³>32⁹

vậy (-18)¹³ <(-32)⁹

(-32)⁹=-(32⁹)

(-18)¹³=-(18¹³)

32⁹<36⁹

ta có :36⁹=(2\(\times\)18)⁹=2⁹\(\times\)18⁹

vì 18⁴>16⁴mà 16⁴=(2⁴)⁴=2¹⁶

mà 2¹⁶>2⁹

^{\(\Rightarrow\)}18⁴>2⁹

^{\(\Rightarrow\)}18⁴\(\times\)18⁹>2⁹\(\times\)18⁹

\(\Rightarrow\)18¹³>36⁹mà 36⁹ >32⁹

\(\Rightarrow\)18¹³>32⁹

\(\Rightarrow\)(-18)¹³<(-32)⁹
