Объяснение:

1.  10*2:0,4-2.6*(-3) = 50 +7.8 = 50 +7.8 = 57.8.

2.  4.5+5^2*0.4 - 10^2*0.006 = 4.5+25*0.4 - 100*0.006 = = 4.5 + 10 - 0.6 =

= 14.5-0.6 = 13.9.

3.  10^2*0.63 -5^2*0.008 + 4.44 = 100*0.63-25*0.008 + 4.44 =

= 63 - 0.2+4.44 = 62.8+4.44 = 67,24.  

4.  6.8 - 25^2*0.4 - 10^3*0.045 = 6.8-625*0.4-1000*0.045 =

= 6.8-250 - 45 = -243.2 - 45 = -288.2.
