Question

Mohon bantuannnya :)
3log24 - 3log 2v/3 +2 x 3log1/9 + 3log 9/4
note :
v/ = akar

bacaan :
3 log 24 kurang 3 log 2 akar 3 tambah 2 kali 3 log 1 per 9 tambah 3 log 9 per 4

sertakan caranya terima kasih :)

Answer 1

3 log 24 - 3 log √3 + (2.-2) + 3 log 9/4
= 3 log (24 . 9 /.4) - 3 log √3  - 4
= 3 log 54   - 3 log √3  - 4
= 3 log 3 + 3 log 16  - 3 log √3  - 4
= 1 - (1/2) - 4 + 3 log 16
= -7/2 + 3 log 16

Answer 2

3log24 - 3log 2v/3 +2 x 3log1/9 + 3log 9/4
= 3 log (24 / 2v/3)(1/81 x 9/4)
= 3 log (24 / 2.3^1/2) (9/324)
= 3 log (2^3.3/2.3^1/2)(1/36)
= 3 log (2^2. 3^1/2)(1/3^2.2^2)
= 3 log (4/3^5/2.4)
 =  log 1/3^5/2= 3^x
= log 3^-5/2 = 3^x
jadi x = - 5/2
