Answer 1

$1)0.4 \times 17 \times 2.5 = 17 = 1.7 \times 10 {}^{1} \\ 2)0.125 \times 4.3 \times 80 = 43 = 4.3 \times 10 {}^{1} \\ 3)0.05 \times 6.73 \times 0.2 = 0.0673 = 6.73 \times 10 {}^{ - 2} \\ 4)0.4 \times 0.36 \times 5 = 0.72 = 7.2 \times 10 {}^{ - 1}$

Answer 2

1.0,4×17 ×2,5=17

1)0,4*2,5=4/10*5/2=2/5*5/2=1

2)1*17=17

2.0,125*4,3*80=

1)0,125*80=10

2)4,3*10=43

3.0,05*6,73*0,2=(0,05*0,2)*6,73=0,01*6,73=0,0673

4.0,4*0,36*5=(0,4*5)*0,36=2*0,36=0, 72
