Answer 2

Sure, let's solve these mathematical expressions step by step:

1. $14.3 \cdot 0.6 - 5.7 \cdot 1.4$

$14.3 \cdot 0.6 = 8.58$
$5.7 \cdot 1.4 = 7.98$

Now subtract:

$8.58 - 7.98 = 0.6$

2. $(54 - 23.42) \cdot 0.08$

$54 - 23.42 = 30.58$
$30.58 \cdot 0.08 = 2.4464$

3. $(4.125 - 1.6) \cdot (0.12 + 7.3)$

$4.125 - 1.6 = 2.525$
$0.12 + 7.3 = 7.42$
$2.525 \cdot 7.42 = 18.74845$

4. $(139 - 23.48) \cdot 38 + 4.35 \cdot 18$

$139 - 23.48 = 115.52$
$115.52 \cdot 38 = 4388.16$
$4.35 \cdot 18 = 78.3$

Now add the results:

$4388.16 + 78.3 = 4466.46$

So, the results are:

1. $0.6$
2. $2.4464$
3. $18.74845$
4. $4466.46$
