Question

Dados log 2 = 0,30 log 3 = 0,47 quanto vale log 1800

Answer 1

Calcule: (a) log2 16 (b) log3 81 (c) log5 125 (d) log6 1296 (e) log12 1728 (f) log2 4096 (g) log28 1 √ 1 (j) log 100 (k) log2 1024 (l) logπ π (m) log4 16 (n) log3 (h) log5 625 (i) log2 2 9 1 1 (q) log7 (r) log125 5 (s) log 1 32 (t) log9 (u) log27 81 (o) log81 3 (p) log 1 8 2 2 7 27 √ (v) log√8 32 Exercício 2. Usando apenas que log 2 = 0, 30, log 3 = 0, 47 e log 5 = 0, 69, calcule: √ 2 3 (a) log 4 (b) log (c) log 12 (d) log 25 (e) log 2 (f) log 0.5 (g) log (h) log 20 5 2 10 (n) log 10 (o) log2 5 (i) log2...

Answer 2

Log 1800= log100 + log 3 + log 3 + log 2
Log 1800= 2+ 0,47+ 0,47+ 0,30
Log 1800=3,24
