Question

Jika log 2 = 0,3010 , log 3 = 0,4771 , log 5 = 0,6990 dan log 7 = 0,8451.Maka tentukan nilai dari log 6 , log 21 , log 25 , log 15 , log 42 , log 70 ,dan log 84 ?

Answer 1

Log 6 = log 2 +log 3=0,7781
log 21 = log 7 + log 3= 1,3222
log 25 = log 5 + log 5= 1,398
log 15 = log 5 + log 3 = 1,1761
log 42 = log7 + log 3+ log 2= 1,6232
log 70 = log 7 + log 5 + log 2= 1,8451

kalo salah maaf ya...
