Question

Assunto Logaritmo !!!

Answer 1

3) log(E) = 1 + log(a) + 2log(b) - log(c)        
    E = 10a*b²c

 4) log(8) = a , log(3) = b  
     log(8) = log(2^3) = 3log(2), log(2) = a/3
     log(³√18) = log(18)/2 = log(2)/2 + 2log(3)/2       
     log(³√18) = a/6 + b

  5)  log2(7) = log(7)/log(2)       
       log100(3) = log(3)/log(100) = log(3)/2
