Задание на тест, заранее спасибо.

Answer 1

$frac{625 {c}^{2} d}{0.04 {a}^{3}b } = frac{15625 {c}^{2} d}{ {a}^{3}b } \ \ log_{5}(frac{15625 {c}^{2} d}{ {a}^{3}b }) = log_{5}(15625) + log_{5}( {c}^{2} ) + log_{5}(d) - log_{5}( {a}^{3} ) - log_{5}(b) = \ \ = 6 + 2 log_{5}(c) + log_{5}(d) - 3 log_{5}(a) - log_{5}(b)$
