Question

Jika log 2=0,3010 dan log 5 = 0,69990 maka log 500 adalah?

Answer 1

Log2 = 0,3010
log 5 = 0,69990
log 10 = 1
log 100 = 2


log 500 = log (5 x 100)
log 500 = log 5 + log 100
log 500 = 0,69990 + 2 = 2,69990

atau
log 500 = log(75 x4)
log 500 = log 75+log 4
log 500 = log 5³+log2²
log 500 = 3 log 5 + 2 log 2
log 500 = 3 (0,69990) + 2(0,3010)
log 500 = 2,0997 + 0,602
log 500 = 2,69990
