Question

Utilizand regulile de calcul cu puteri, efectueaza calculele:
25 23 23 21
a) 4 :4 -3 :3 =
25 23
b) (14-11) :(23-20) =
3 8 6 4
c) (3 ) :3 ×3 =
3 3 23 20
d) 24 :6 -4 :4 =
176 0 24 199
e) 5 ×5 ×5 :5 =
24 24 24
f) 2 ×3 -6 =
7 8 9 6
g) (5 +5 +5 ):5 =
4 5 6
h) (7 +2×7 +3×7 ):162

Answer 1

a) 4:4 - 3:3 = 1-1= 0
b) (14-11):(23-20)= 3 : 3 = 1
c) 3:3×3= 1×3=3
d) 24:6-4:4 = 4 - 1 = 3
e) 5×5×5:5 = 125:5= 25
f) 2×3-6= 6-6= 0
g) (5+5+5) : 5= 15:5 = 3
h) (7+2×7+3×7):162 = (7+14+21):162= 42: 162
Ultimul h) nustiu daca e bine scris in carte sau daca l-ai scris tu corect ..dar nu se imparte 42 la 162 . Bafta!
