Log 28 = log(2^2x7) = log2^2+log7 = 2log2+log7 = 2(0,3010)+(0,8451)
log 42 = log(2x3x7) = log2+log3+log7= 0,3010 + 0,4771 + 0,8451
log 49 = log7^2 = 2log7 = 2(0,8451)
Log 63 = log(3^2x7) = log3^2+log7 = 2log3+log7 = 2(0,4771)+(0,8451)
hitung sendiri ya
= 3 log 2 + log 3
= 3(0,3010) + 0,4771
= 1,3801
log 28 = log (2^2 x 7)
= 2 log 2 + log 7
= 2(0,3010) + 0,8451
= 1,4471
log 42 = log (2x3x7)
= log 2 + log 3 + log 7
= 0,3010 + 0,4771 + 0,8451
= 1,6232
log 49 = log (7^2)
= 2 log 7
= 2(0,8451)
= 1,6902
log 63 = log (3^2 x 7)
= 2 log 3 + log 7
= 2(0,4771) + 0,8451
= 1,7993
