Explicație pas cu pas:

35⁽⁵/5⁽⁵√3

= 7/√3

=7√3/3

b)

-36⁽⁴/4⁽⁴√5

=-9 /√5

=- 9√5/5

-

c)

-33⁽³/ -3⁽³√11

= 11/√11

= 11⁽¹¹√11 / 11⁽¹¹

=√11

-

d)

10⁽⁵ / 15⁽⁵√3

= 2 /3√3

= 2√3 /3*√3*√3

=2√3 / 3*3

= 2√3/9

Answer 2

$\it a)\ \ \dfrac{\ 35^{(5}}{5\sqrt3}=\dfrac{^{\sqrt3)}7}{\ \ \sqrt3}=\dfrac{7\sqrt3}{3}\\ \\ \\ b)\ \ -\dfrac{\ 36^{(4}}{5\sqrt3}=-\dfrac{^{\sqrt5)}9}{\ \ \sqrt5}=-\dfrac{9\sqrt5}{5}\\ \\ \\ c)\ \ \dfrac{-33^{(-3}}{-3\sqrt{11}}=\dfrac{^{\sqrt{11})}11}{\ \ \sqrt{11}}=\dfrac{11\sqrt{11}}{11}=\sqrt{11}$
