Question

determine E=log10 ^4 /1000 -log4 (16)+log7 (7*)​

Answer 1

Resposta:

E = 3/4

Explicação passo-a-passo:

$= log( \sqrt[4]{1000} ) - log_{4}(16) + log_{7}( {7}^{2} ) \\ \\ = log( {( {10}^{3}) }^{ \frac{1}{4} } ) - log_{4}( {4}^{2} ) + 2 log_{7}(7) \\ \\ = log( {10}^{ \frac{3}{4} } ) - 2 log_{4}(4) + 2(1) \\ \\ = \frac{3}{4} log(10) - 2(1) + 2(1) \\ \\ = \frac{3}{4}$
