(42-149.1:14.2)*5.3+6.15
1)149.1:14.2=10.5
2)42-10.5=31.5
3)31.5*5.3=166.95
4)166.95+6.15=173.1
Ответ:173.1
3) 7/8 = 0.875 18/100 =9/50 7-3=4
4) 7/8-9/50=4 (25-36)/200=3 89/200 три целые а не 6
4) 4 3/4=4 12/16 4 12/16-2 3/16=2 9/16
F(x) = 5x⁴ - 2x +1
F(x) = 5 · x⁵/5 - 2 · x²/2 + x + C = x<span>⁵ - x</span>² + x + C
