2.Hitunglah : a) log 1.000 + log 10.000 + log 10- log 100, b) ^2 log 50 - ^2 log 25 + ^2 log 40, c) ^3 log 1/6 + ^3 log 54 + ^3 log 54 + ^3 log 108 - ^3 log 4 ½
3.Diketahui log 2 = 0.301 dan log 3 + 0.477 hitunglah nilai dari : a) log 12, b) log 24, c) log 3/8, d) log 72
4.Diketahui 63 log 7=a, ^5 log 2=b, ^2 log 3=c. nyatakanlah a) ^7 log 3, b) ^4 log 5.
2.Hitunglah : a) log 1.000 + log 10.000 + log 10- log 100, b) ^2 log 50 - ^2 log 25 + ^2 log 40, c) ^3 log 1/6 + ^3 log 54 + ^3 log 54 + ^3 log 108 - ^3 log 4 ½
3.Diketahui log 2 = 0.301 dan log 3 + 0.477 hitunglah nilai dari : a) log 12, b) log 24, c) log 3/8, d) log 72
4.Diketahui 63 log 7=a, ^5 log 2=b, ^2 log 3=c. nyatakanlah a) ^7 log 3, b) ^4 log 5.
a. 2 + 4 = 6
b. 3 + 6 = 9
c. 2 + 1 - 0 = 3
2.
a. 3 + 4 + 1 - 2 = 6
b. 2log50.40/25= 2log80
c. 3log(1/6.54.108÷9/2)= 3log216=6
3. log2=0.301 log3=0.477
a. log12 =
log3 + log2 + log2 =
0.301 + 0.301 + 0.477 = 1.079
b. log24
log3 + log3 + log2 + log2 = 1.556
c. log3/8
log3 - 3. log2 = - 0.426
d. log72
2. log 3 + 3. log 2 = 1.857
