Ctt : yg no 4 mgkn mksd anda  2_{log}7 = b
4a.  2_{log}98 =  2_{log}2x49 =   2_{log} 2 +  2_{log} 7^{2}=1+2. 2_{log}7 = 1 +2b

4b.  8_{log}49 =   2^{3} _{log} 7^{2} =  \frac{2}{3}x   2_{log} 7  =  \frac{2}{3}b

5a. 2 x 2_{log}9 = 2x  2_{log} 3^{2}= 4 x  2_{log}3

5b. 8x  2_{log}25 = 8x  2_{log} 5^{2}= 16x  2_{log}5

6.  2_{log}6 =  2_{log}2x3 =  2_{log} 2 +  2_{log}3 = 1 + 10 = 11

kalau ditulis dalam buku, gk usah ditulis tanda x nya, dsini sengaja dibikin supaya gk dempet keliatannya
eh bukan, bikin titik aja, sama seperti tanda perkalian
yang nomer 6 jawabannya berapa ya?
11
oke makasih banyak yaaa
