berapa hasilnya pake cara

6. 3log 1/81 = 3log 1 - 3 log 81
                    = 0 - 3log 3^4
                    = 0 - 4 x 3log 3
                    = -4

7. 5 log 1/25 = 5log 25^-1
                     = 5 log (5^2)^-1
                     = 5 log 5^-2
                     = 1 x (-2)
                     = -2

8. 2log √32 = 2log 32^1/2
                   = 2log (2^5)^1/2
                   = 2 log 2^5/2
                   = 5/2 = 1 1/2 = 1,5
9. 3log √27 = 3log √3^3
                   = 3 log 3^3/2
                   = 3/2 x 3log 3
                   = 3/2 x 1
                   = 3/2 = 1 1/2 = 1,5

10. 5 log √625 = 5log √25^2
                        = 5 log 25
                        = 5log 5^2
                        = 2


Semoga Membantu,,,,,
