63^15<34^18

ra loi giai di

63^15<64^15=(2^6)^15=2^90=(2^5)^18=32^18<34^18

63 ^15 = 60 ^ 5*3 = (65^5 ) ^3 = 992436543^3

34^18 = 34 ^6*3 = (34^6)^3 = 1544804416^3

vì  992436543^3 < 1544804416^3

=> 63 ^ 15 < 34 ^ 18 

k mk nha mn 

Ta có:

 \(63^{15}< 64^{15}\)

\(=\left(2^6\right)^{15}\)

\(=2^{90}\)

\(=\left(2^5\right)^{18}\)

\(=32^{18}< 34^{18}\)

\(\Rightarrow63^{15}< 34^{18}\)

63=3^2.7 

mà bạn

mk ko biết giai thông cảm

63^15<34^18

63 ^15 = 63^ 5.3 = ( 63^ 5 ) 3 = 992 436 543^ 3

34 ^18 = 34^ 6.3 = ( 34^ 6 ) 3 = 1 544 804 416 ^3

Vì : 992 436 543^ 3 < 1 544 804 416^ 3

Nên : 63 ^15 < 34^ 18 

63 mũ 15 >34 mũ 18

thanks

63¹⁵>34¹⁸

\(63^{15}< 64^{15}=\left(2^6\right)^{15}=2^{90}=\left(2^5\right)^{18}=32^{18}< 34^{18}\)

\(63^{15}=\left(63^5\right)^3=992436543^3\)

\(34^{18}=\left(34^6\right)^3=1544804416^3\)

\(992436543< 1544804416\Rightarrow992436543^3< 1544804416^3\)

\(\Rightarrow63^{15}< 34^{18}\)

63\(^{15}\)lớn hơn 34\(^{18}\)

Ta có: \(63^{15}< 64^{15}\Rightarrow63^{15}< \left(2^6\right)^{15}\Rightarrow63^{15}< 2^{90}\)

          \(34^{18}>32^{18}\Rightarrow34^{18}>\left(2^5\right)^{18}\Rightarrow34^{18}>2^{90}\)

Suy ra: \(63^{15}< 2^{90}< 34^{18}\)

Vậy \(34^{18}>63^{15}\)

Ta có: \(63^{15}< 64^{15}=\left(2^6\right)^{15}=2^{90}=\left(2^5\right)^{18}=32^{18}< 34^{18}\)

\(\Rightarrow63^{15}< 34^{18}\)

\(63^{15}< 64^{15}=\left(2^6\right)^{15}=2^{6.15}=2^{90}\)

\(34^{18}>32^{18}=\left(2^5\right)^{18}=2^{5.18}=2^{90}\)

Vậy \(63^{15}< 34^{18}\)

63¹⁵ = 63^3.5 = (63⁵)³ = 992436543³

34¹⁸ = 34^3.6 = (34⁶)³ = 2176782336³

=> 63¹⁵ <34¹⁸

c.ơn nhìu nha

63¹⁵ = 63^5.3 = ( 63⁵ )³ = 992 436 543³

34¹⁸ = 34^6.3 = ( 34⁶ )³ = 1 544 804 416 ³

Vì : 992 436 543³ < 1 544 804 416³

Nên : 63¹⁵ < 26¹⁸

83⁹ = 83^3.3 = ( 83³ )³ = 571 787³

26¹² = 26^{4.3 =} ( 26⁴ )³ = 456 978³

Vì : 571 787³ > 456 978³

Nên : 83⁹ > 26¹²

63¹⁵ <64¹⁵

34¹⁸<36¹⁸

64¹⁵=8³⁰ =(2.4)³⁰

36¹⁸=6³⁶
