Log 3 = 0, 4771. nilai log √0, 3

Log (akar 0,3)
log (akar 3/10)
log (akar 3) – log (akar 10)
log 3^1/2 – log 10^1/2
(0,5 x 0,4771)- 0,5
0,23855 -0,5
-0,26145

Log akar 0,3 = log 0,3 pangkat 1/2
= 1/2 log 0,3
= 1/2 log (3×10^-1)
= 1/2 (log 3 + log 10^-1)
= 1/2. ( 0,4771 + (-1))
= 1/2 .-0,5229
= -0,26145
