Answer 1

Explicație pas cu pas:

a) 26 × 2 = 13 × 4

26 × 2 = 52

13 × 4 = 52

26 × 2 = 13 × 4 (adevărat)

----------------------------------

b) 87 × 4 = 58 × 64

87 × 4 = 348

58 × 64 = 3712

87 × 4 = 58 × 64 (fals)

----------------------------------

c) 58 × 5 = 7 × 41

58 × 5 = 290

7 × 41 = 287

58 × 5 = 7 × 41 (fals)

----------------------------------

d) 25 × 4 = 3 × 35

25 × 4 = 100

3 × 35 = 105

25 × 4 = 3 × 35 (fals)
