Explicação passo-a-passo:

$\boxed{log_{1,25}0,64 = (\frac{125}{100} )^x = \frac{64}{100} }}$

$\boxed{(\frac{125}{100} )^x = \frac{64}{100} }}$

$\boxed{(\frac{5}{4} )^x = \frac{16}{25} }}$

$\boxed{(\frac{5}{4} )^x = \frac{4^2}{5^2} }}$

$\boxed{(\frac{5}{4} )^x = (\frac{5}{4})^{-2} }}$

$\boxed{\boxed{x = -2}}$
