Explicação passo a passo:

$\mathsf{log_x\:\dfrac{1}{16} = 2}$

$\mathsf{x^2 = \dfrac{1}{16}}$

$\mathsf{x^2 = \left(\dfrac{1}{4}\right)^2}$

$\boxed{\boxed{\mathsf{x = \dfrac{1}{4}}}}$

$\mathsf{log_{\frac{1}{2}}\:32 = x}$

$\mathsf{\left(\dfrac{1}{2}\right)^x = 32}$

$\mathsf{\not2^{-x} = \not2^5}$

$\boxed{\boxed{\mathsf{x = -5}}}$
