Nilai 2(log 0,04 + log 0,25) adalah

ImmanuelSinaga $\bold{2(log~0,04~+~log~0,25)~~=~~2(log~(0,04~\times~0,25))} \\ \\ \bold{2(log~0,04~+~log~0,25)~~=~~2(log~(0,01))} \\\\ \bold{2(log~0,04~+~log~0,25)~~=~~2(log~(\frac{1}{100}))} \\ \\ \bold{2(log~0,04~+~log~0,25)~~=~~2(log~(10^{-2}))} \\ \\ \bold{2(log~0,04~+~log~0,25)~~=~~2(-2~\times~log~(10))} \\ \bold{2(log~0,04~+~log~0,25)~~=~~-4}$

karoindahritong makasih hasilnya memuaskan kak,bisa tanyak lagi nggak?

ImmanuelSinaga boleh

ImmanuelSinaga silakan ajukan pertanyaan , di kolom "Ajukan Pertanyaan" agar hasil lebih jelas

ImmanuelSinaga Jika lewat komentar kurang jelas

alvinteguh 2(log (4/100) + log(25/100))
= 2(log (4/100 . 25/100))
= 2(log (100/10000))
= 2(log (1/100))
= 2(log (10^-2))
= 2(-2 . log 10)
= 2(-2 . 1)
= 2.-2 = -4
