Oblicz:
a) (-2√3) do potegi -2
b) (3/√2) do potęgi -4
c) ( - √5/10) do potęgi -3
d)((-3√2) do potęgi -1)do potęgi -2)
Jest to zadanie 4/35 Matematyka nowa era do 1 LICEUM!
Będę bardzo wdzięczna za pomoc :)

a) (-2√3) ⁻²=(-1/2√3)² = 1/4*3 = 1/12
b) (3/√2) ⁻⁴ =( √2/3)⁴ = 4/81
c) ( - √5/10)⁻³ = (-10/√5)³ = -1000/5√5 = -(1000*5√5)/(5√5)² = -5000√5/125 = -40√5
d)((-3√2)⁻¹)⁻²)=(-3√2)² =9*2=18
