Se considera numarul a= (1,2 la puterea 3 : 0,9 - 1,2) :0,06.

Answer 1

a=(1,2^3:0,9-1,2):0,06
a=(1,728:0,9-1,2):0,06
a=(1,92-1,2):0,06
a=0.72:0,06
a=12

Answer 2

1,2 la puterea 3 =1,728=1728/1000 care simplificat la 8 da 216/125
0,9=9/10
1,2=12/10 care simplificat la 2 da 6/5
0,06=6/10 care simplificat la 2 da 3/5
216/125:9/10=216/125*10/9=432/255
432/255-6/5( 6/5 il transformam in 306/255 ) = 126/255
126/255:3/5=126/255*5/3=42/51
