Answer 1

a) 2⁵, 7²

2⁵ = 2 × 2 × 2 × 2 × 2 = 4 × 2 × 2 × 2 = 8 × 2 × 2 = 16 × 2 = 32

7² = 7 × 7 = 49

Media aritmetică:

$\frac{32 + 49}{2} = \frac{81}{2} = 81 \div 2 = 40.5$

b) 3⁴, 6²

3⁴ = 3 × 3 × 3 × 3 = 9 × 3 × 3 = 27 × 3 = 81

6² = 6 × 6 = 36

Media aritmetică:

$\frac{81 + 36}{2} = \frac{117}{2} = 117 \div 2 = 58.5$

c) 5³, 2⁴

5³ = 5 × 5 × 5 = 25 × 5 = 125

2⁴ = 2 × 2 × 2 × 2 = 4 × 2 × 2 = 8 × 2 = 16

Media aritmetică:

$\frac{125 + 16}{2} = \frac{141}{2} = 141 \div 2 = 70.5$

d) 3³ = 2⁶

3³ = 3 × 3 × 3 = 9 × 3 = 27

2⁶ = dacă 2⁵ = 32 atunci, 32 × 2 = 64

Media aritmetică:

$\frac{32 + 64}{2} = \frac{96}{2} = 96 \div 2 = 48$
