Question

log de 432 na base 2 ,sendo log de 2=x

Answer 1

 Propriedades utilizadas:

• $Log_ab = \frac{Log_cb}{Log_ca}$
• $Log_a(x.y)=Log_ax+Log_ay$

$Log_2432\\\\\frac{Log432}{Log2}\\\\\frac{Log(16.27)}{x}\\\\\frac{Log16+Log27}{x}\\\\\frac{Log2^4+Log3^3}{x}$

$\frac{Log2^4+Log3^3}{x}\\\\\frac{4.Log2+3.Log3}{x}\\\\\frac{4.x+3.Log3}{x}\\\\4+\frac{3.Log3}{x}$
