Question

EŚLI MOŻEsZ TO ROZWIĄŻ POTEGOWNIE: znak ^ znaczy o potędze np. 2^3=8

(-2) ^-2=

(3: 2^3)^-1 =

(1,5)^3 =

-(-1/3)^-1 =

-(0,1)^1

Answer 1

(-2) ^-2= (-1/2)² = 1/4

(3: 2^3)^-1 = (3:8)⁻¹ = (3/8)⁻¹ = (8/3)¹ = 8/3 = 2 2/3

(1,5)^3 = (3/2)³ = 27/8 = 3 3/8

-(-1/3)^-1 = -(-3)¹ = -(-3) = 3

-(0,1)^1 = -0,1
