Question

Найдите значение выражения
81 в степени 1/4 - (3√3)*2 

Answer 1

81^1/4-(3√3)²=(3^4)^1/4 -(3√3)²=3-9*3=3-27=-24

Answer 2

$81^frac{1}{4}-(3sqrt3)cdot2=sqrt[4]{81}-6sqrt3=sqrt[4]{3^4}-6sqrt3=3-6sqrt3=3(1-2sqrt3)$

----------------------------------------------------------------------------------------------------------------

$81^frac{1}{4}-(3sqrt3)^2=sqrt[4]{81}-3^2cdot(sqrt3)^2=sqrt[4]{3^4}-9cdot3=3-27=-24$
