Question

No. 1 yg b sama c gmn???

Answer 1

B) log 41/35+ log 70 - log 41/2 + 2 log 5
    = log 41 - log 35 + log (35x2) - (log 41 - log 2) + 2 log 5
    = log 41 - log 35 + log 35 + log 2 - log 41 + log 2 + 2 log 5
    = 2 log 2 + 2 log 5
    = 2 (log 2 + log 5)
    = 2 (log 10)
    = 2 x 1 = 2

c) cara terlampir
