5^36=(5^3)^12 = 125^12

11^24 =( 11^2 ) ^12 = 121^12

do 125^12>121^12 nên 5^36 > 11^24

câu cò lại tương tự

\(a,4^{333}=\left(4^3\right)^{111}=64^{111}< 81^{111}=\left(3^4\right)^{111}=3^{444}< 3^{445}\\ b,39^{15}>36^{15}=\left(6^2\right)^{15}=6^{30}\\ c,25^{45}=\left(5^2\right)^{45}=5^{90}< 5^{102}=\left(5^3\right)^{34}=125^{34}\)

a) \(81^{40}=\left(3^4\right)^{40}=3^{160}\)

   \(27^{14}=\left(3^3\right)^{14}=3^{42}\)

Vì \(3^{160}>3^{42}\) => \(81^{40}>27^{14}\)

b) \(5^{64}=5^{4.16}=625^{16}\)

   \(3^{96}=3^{6.16}=729^{16}\)

Vì \(625^{16}< 729^{16}\)=> \(5^{64}< 3^{96}\)

c) \(125^{12}=\left(5^3\right)^{12}=5^{36}\)

   \(25^{10}=\left(5^2\right)^{10}=5^{20}\)

Vì \(5^{36}>5^{20}\)=> \(125^{12}>25^{10}\)

T_i_c_k nha,mơn bạn nhìu ^^

a, 81⁴⁰>27¹⁴

b, 5⁶⁴<3⁹⁶

c, 125¹²<25¹⁰

a. 81⁴⁰  lớn hơn 27¹⁴

b. 5⁶⁴ bé hơn 3⁹⁶

^c. 125¹² lớn hơn 25¹⁰

k cho mk nhá

a, (-0,2)² \(\times\) 5 - \(\dfrac{2^{13}\times27^3}{4^6\times9^5}\)

= 0,04 \(\times\) 5 - \(\dfrac{2^{13}\times3^9}{2^{12}\times3^{10}}\)

= 0,2 - \(\dfrac{2}{3}\)

= \(\dfrac{2}{10}\) - \(\dfrac{2}{3}\)

=  - \(\dfrac{7}{15}\)

b, \(\dfrac{5^6+2^2.25^3+2^3.125^2}{26.5^6}\)

 = \(\dfrac{5^6+4.5^6+8.5^6}{26.5^6}\)

= \(\dfrac{5^6.\left(1+4+8\right)}{26.5^6}\)

= \(\dfrac{1}{2}\)

a, (-0,2)2 $\times$ 5 - 213×27346×9546×95213×273​

= 0,04 $\times$ 5 - 213×39212×310212×310213×39​

= 0,2 - 2332​

= 210102​ - 2332​

=  - 715157​

b, 56+22.253+23.125226.5626.5656+22.253+23.1252​

 = 56+4.56+8.5626.5626.5656+4.56+8.56​

= 56.(1+4+8)26.5626.5656.(1+4+8)​

= 1221​
 

a, Ta có:\(8^{10}=\left(2^3\right)^{10}=2^{30}\)

          \(1024^3=\left(2^{10}\right)^3=2^{30}\)

Vậy \(8^{10}=1024^3\)

b, Dựa theo ý a nhưng cơ số là 5\(\Rightarrow25^7>125^3\)

c,  Ta có: \(49^{10}\)giữ nguyên

\(625^5=\left(25^2\right)^5=25^{10}\)

Cảm ơn bạn Trần Hải Nam nha 

a: \(5^{300}=25^{150}\)

\(3^{450}=27^{150}\)

mà 25<27

nên \(5^{300}< 3^{450}\)

a: 5300=251505300=25150

3450=271503450=27150

mà 25<27

nên 5300<3450
