Question

Tolong bantuin aku dong yg 7 soal ini.. aku gk ngerti pleaseee pakai cara ya

Answer 1

1/3. 5log125 - 2. 2log4 + 2log32 = 1/3. 5log5*3 - 2. 2log2*2 + 2log2*5 =
3.1/3. 5log5 - 2.2. 2log2 + 5. 2log2 =
1-4+5 = 2

Answer 2

2. langsung ke jawabnya aja...
(1/ akar 9 - akar 8) × (akar 9 + akar 8/ akar 9 + akar 8) =
akar 9 + akar 8/ 1

3. 2log 8 + 3log 9 + 5log 125 =
3 + 2 + 3 = 8

4. 5log akar 27 × 9log 125 + 5log 125 =
3/2 5log 3 × 3log 5 + 5/4 2log 2 =
5log 3 × 3log 5 × 2log 2 =1
3/2 + 5/4 = 6/4 + 5/4 = 11/4

5. langsung aja ya?
5log 5^-1/2 + 3log 3^-1 - 2log 64=
-1/2 - 1 - 6 = -15/2

6. langung aja ya? gak usah pake soal...
akar 27 × akar 48 : 4 = akar 1296 : 4 = 36:4 = 9

sorry klo krg jelas, dan sorry klo salah...
