Answer 1

(2)*-3 x (5)*-3=(2x5)*-3=(10)*-3=1/1000

(4)*-2 x(15)*-2=(4x15)*-2=(60)*-2= 1/3600

(1/4)*-5 x (8)*-5=(1/4 x 8)* -5=(2)*-5=1/32

(2,8)*-1 x (10)*-1= (2,8 x 10)*-1=1/28

(3/5)*-2 x (1 2/3)*-2= (1)*-2=1

(-0,15)*-3 x (6)*-3= (-0,15 x 6)*-3= (- 0,9)*-3 =(- 9/10)*-3=-729/1000

6^-2 : 2^-2= (6/2)^-2= 1/9

10^-5 : 5^-5= (10/5)^ -5 = 1/32

48^-1 :2^-1=( 48/2)^-1= 1/24

30^-3 : 3^-3= (30/3)^-3= 1/1000

(-15)^-3 : (-5)^-3= (3)^-3= 1/27

18^-8 : (-9)^-8= (-2)^-8= 1/256
