Question

Dados log2 = 0,30 e log3 = 0,47. Calcule log 4√3.

Answer 1

$log 4 \sqrt{3} = log 4 + log \sqrt{3} = log 2^{2}+ log 3^{ \frac{1}{2} } \\ \\ 2log 2 + \frac{1}{2} log 3 = 2.0,30+ \frac{1}{2} .0,47 \\ \\ 0,60+ \frac{0,47}{2} = \frac{(1,2+0,47)}{2} = \frac{1,67}{2} =0,835$

Espero ter ajudado.
