hasilnya nol ya?bener gak??maklum..bukan ahli matematika..eehehe
ReplyDeleteHehe... Dapet nol darimana nieh? Kalku? Bisa dijelaskan? :D
ReplyDeletesaya tertarik dng blog ini,
ReplyDeletekebetulan sy sedang be;ajar mtk
u/ perispan olimpiade
2^(10log 2009)=2^(2log2009/2log10)
ReplyDelete=2009^(1/2log10)=2009^(10log2)
begitu juga dengan soal no 2 dan 3
semuanya menggunakan sifat logaritma alog b= clog b/ clog a
dan alog b = 1 / blog a
bener gak??hehe
@atas: iya..
ReplyDeleteLebih mudahnya lagi, dari persamaan:
p^ log q - q ^ log p = 0, cukup memisalkan:
q = p^k, di mana k adalah sembarang...
Maka, .... (coba uraikan sendiri)
jelas nol karena dikurang klo di kali hasilnya berapa?
ReplyDeletehaduh boz bingung ni tapi posting nya bagus bisa buat belajar hehehe.....
