a)
b)
c) 10*0,0001-0,1*10000= 0,001-1000= -999,999
d)
Odpowiedź:
(1/3)² - (-1/3)³ = 1/9 + 1/27 = 3/27 + 1/27 = 4/27
(2/7)² - 2²/7 + 2/7² = 4/49 - 4/7 + 2/49 = 6/49 - 28/49 = -22/49
c)
10 * (-0,1)^4 - 0,1 * 10^4 = 10 * 0,0001 - 0,1 * 10000 = 0,001 - 1000 = -999,999
3² * 1/3 - (-1/3)^0 * (-3)² = 9 * 1/3 - 1 * 9 = 3 - 9 = -6
