Question

81^1/6•81^1/3•81^-1/4

Answer 1

Ответ:

= 3

Пошаговое объяснение:

${81}^{ \frac{1}{6}} \times {81}^{ \frac{1}{3}} \times {81}^{ - \frac{1}{4}} =$

$= {81}^{ \frac{1}{6} + \frac{1}{3} + ( - \frac{1}{4})} = {81}^{ \frac{1 + 2}{6} - \frac{1}{4}} =$

$= {81}^{ \frac{1}{4}} = {( {3}^{4})}^{ \frac{1}{4}} = {3}^{4 \times \frac{1}{4} } =$

$= {3}^{1} = 3$
