(12*(-0,5))² = (-6)² = 36
(-14*(-1))² = 14² = 196
(-6/1,5)³ = (-4)³ = -64
(0/(-23))³ = 0³ = 0
(0,7+0,3)⁴ = 1⁴ = 1
(-11+6)⁴ = (-5)⁴ = 625
(-10-(-14))³ = (-10+14)³ = 4³ = 64
(1,1-0,9)³ = 0,2³ = 0,008
1)(xy)^2= (12*-0.5)^2=-6^2=36;=(-14*-1)^2=14^2=196
2)(x/y)^3=(-6/1.5)^3=(-4)^3=-64;=(0/-23)^3=0^3=0
3)(x+y)^4=(0.7+0.3)^4=1^4=1;=(-11+6)^4=(-5)^4=625
4)(y-x)^3=(-14+10)^3=(-4)^3=-64;=(0.9-1.1)^3=(-0.2)^3=-0.008
