Question

RESOLVA O LOGARITMO:
Log9a √27=1/2

Answer 1

$log9a  \sqrt{27} = 1/2$

aplicando a definição de log :

$(9a)^ \frac{1}{2} = \sqrt{27}$

$(\sqrt{9a})^2 = (\sqrt{27})^2$

$9.a = 27\\a = 3$

Answer 2

Resposta:

$\textsf{Leia abaixo}$

Explicação passo a passo:

$\mathsf{log_{9a}\:\sqrt{27} = \dfrac{1}{2}}$

$\mathsf{\sqrt{9a} = \sqrt{27}}$

$\mathsf{3\sqrt{a} = 3\sqrt{3}}$

$\boxed{\boxed{\mathsf{a = 3}}}$
