Odpowiedź:
a) (-3/4) ² > (3/4)³
bo: (-3/4) ²= 9/16= 36/64 i ( 3/4)³= 27/64
b) (-0,6) ² = (3/5)²
bo:
(-06)² =( -6/10)² i (3/5) ²= ( 6/10)²
(-6/10)2= 36/100 i (6/10)²= 36/100
c) -2, 705 > - 2, 750
d) 1,3 < (1,3)
Szczegółowe wyjaśnienie:
" Life is not a problem to be solved but a reality to be experienced! "
