Question

Mohon bantuannya nomer 1 dan 2 :)​

Answer 1

Jawab:

1)  [ (1 .2.4  + 2.4. 8 + ... + n. 2n. 4n ) / (1.3.9 + 2. 6. 18 + ... + n. 3n. 9n ) ]^(1/3)

= {(n 2n , 4n)/(n. 3n. 9n) }^(1/3)

= (8n³/27n³) ^(1/3)

= (8/27) ^1/3

= ((2/3)³)^¹/³

= (2/3)

2)  

a = 37¹⁵⁰ = (37³)⁵⁰=  (50.653)⁵⁰

b = 215¹⁰⁰ = (215²)⁵⁰ = (46.225)⁵⁰

karena  50.653 > 46.225

maka a > b

Answer 2

Jawaban:

nomor 1. 2/3 dan jawaban nomor 2 a>b
