Betheba 3^4 = 3*3*3*3=81
(-8)²=64
-7²=-49
(0,6)²=0,36
(-0,5)³=0,5*0,5*0,5= -0,125
-(-2/3)³=2/3*2/3*2/3 =6/18
(1/4 )³=1/64
(-1)^7= -1
-(-0,1)^4= 0,1* 0,1* 0,1 *0,1=0,0001

svetazuna 1.
1) 3^4 = 81, (0,6)^2 = 0,36, (1/4)^3 = 1/64,
(1 1/2)^5 = (3/2)^5 = 243/32 = 7 19/32,

2) (-8)^2 = 64, (-0,5)^3 = -0,125, (-1)^7 = -1, (-1/3)^4 = 1/81,

3) -7^2 = -49, -(-2/3)^3 = 8/27, -(-0,1)^4 = -0,0001,

2.
(-9,2)^2 = 84,64 > 0,
(-13,6)^3 = -2515,456 < 0,
-47^5 < 0.
-7,2^2 > 0
