Question

Помогите, надо найти a​

Answer 1

$frac{ {9}^{ frac{1}{3} } times {3}^{ frac{7}{3} } }{ {27}^{5} times {9}^{ frac{a}{3} } } = 3 sqrt[3]{3} \ frac{ {3}^{ frac{2}{3} + frac{7}{3} }}{ {3}^{15 + frac{2a}{3} } } = {3}^{ frac{4}{3} } \ {3}^{frac{2a}{3} - 12} = {3}^{ frac{4}{3} } \ frac{2a}{3} - 12 = frac{4}{3} \ 2a - 4 = 36 \ a = 20$
