Question

Oblicz:

a) (-2√3)do potęgi-3

b) (3/√2)do potęgi-4

c)(-√5/10)do potęgi-3

d) ((3-√2)do potęgi-1)do potęgi-2

Answer 1

a) (-2√3)⁻³=-(2³ * √3³)⁻¹=-(8*3√3)⁻¹=-1/24√3=-√3/72

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

b) (3/√2)⁻⁴=[(3/√2)⁴]⁻¹=(81/4)⁻¹=4/81

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

c)(-√5/10)⁻³=-[(√5/10)³]⁻¹=-(5√5/100)⁻¹=-(√5/20)⁻¹=-20/√5=-4√5

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

d) ((3-√2)⁻¹)⁻²=(3-√2)²=9-6√2+2=11-6√2
