Question

Diketahui log2=0.301 , log3=0.477 , log7=0.845
hitunglah log5 , log6 , log3.5 , log√1.5 , log∛10.5 ,log√6/7
tolong dijawab ya :-)

Answer 1

Diketahui log2=0.301 , log3=0.477 , log7=0.845
hitunglah
log5 = log10/2 = log10 - log2
= 1 - 0,301 = 0,699

 log6 = log2 + log3 = 0,301 + 0,477 = 0,778

 log3.5 = log3 + log 5 = 0,477 + 0,778= 1,255

 , log√1.5 =1/2 (log 1 + log 5)
=1/2 (0 +0,699) = 0,3495
 , log∛10.5= 1/3 (log10 + log5)
=1/3 (1 + 0,699)=0,5663

 ,log√6/7= 1/2 (log 6 - log7)
=1/2(0,778 - 0,845)
=1/2 (-0,067)=-0,0335
