Question

С +с в квадрате + с в кубе -с(1+с) ,если с=0,5

Answer 1

c+c^2+c^3-c(1+c)=c+c^2+c^3-c-c^2=c^3

0,5^3=0.125

Answer 2

0,5+0,5*0,5+0.5*0.5*0.5-0,5*(1+0,5)=0,5+0,25+0,125-0.75=0,125

Answer 3

To evaluate the expression C^2 + C^3 - C(1 + C) when C = 0.5, we substitute the value of C into the expression:

C^2 + C^3 - C(1 + C) = (0.5)^2 + (0.5)^3 - 0.5(1 + 0.5) = 0.25 + 0.125 - 0.5(1.5) = 0.25 + 0.125 - 0.75 = 0.375 - 0.75 = -0.375

Therefore, when C = 0.5, the expression C^2 + C^3 - C(1 + C) evaluates to -0.375.
