Question

Dacă: a = (4x4:4-2)x2
b= 12x2x2:4
c=84:2:2:3
Calculează:
axbxc =
b:ax3xb =
(a + bxc):a=
(a + c)xb=
(b+c+a)xaxc=
(b-c)xaxb=​

Answer 1

Explicație pas cu pas:

a=(16:4-2)×2

a=2×2

a=4

b=24×2:4

b=48:4

b=12

c=42:2:3

c=21:3

c=7

a×b×c=4×12×7=336

b:a×3×b=12:4×3×12=3×3×12=9×12=108

(a+b×c):a=(4+12×7):4=(16×7):4=28

(a+c)×b=(4+7)×12=11×12=132

(b+c+a)×a×c=(12+7+4)×4×7=(19+4)×4×7=23×4×7=92×7=644

(b-c)×a×b=(12-7)×4×12=5×4×12=20×12=240
