Вашему вниманию представлено решение наиболее простых примеров на обобщенную степень:
а) 20=1;
б) (-√2)0=1;
в) (0,1)0=1;
г) 7830=1.
а) (5)-2=1/52=1/25=0,04;
б) 1/(-3)-3=1 / (1/-33)=-33=-27;
в) 1/-11=-1/1=-1;
г)(-1/2)-3=1/(-1/2)3=1/(-1/8)=-8;
д)10-5=1/105=0,00001.
а) 82/3=3√82=4;
б) 125-2/3=1/1252/3=1/3√1252=1/3√56=1/52=1/25=0,04;
в) -4√81=1 / 4√81=1/3;
г) a1/2*a1/3*a1/4 = a1/2+1/3+1/4=a13/12 = 12√a13 =a * 12√a;
д) a1/2:a1/3=a1/2-1/3=a1/6 = 6√a;
е) 3√a*√a = 3√a*a1/2 = 3√a*a3/2=a3/2:3=a1/2;
ж)(x+y-z)3/4=4√a*√(x+y-z)3.
а) (a1/2 + b1/2) (a1/2 - b1/2) = (a1/2)2 - (b1/2)2 = a - b
б) (a1/2+b1/2)2 = a + 2√ab + b
в) a + b = (a1/3)3 + (b1/3)3 = (a1/3 + b1/3) (a2/3 - a1/3 * b1/3 + b2/3)
г) (a+b)/a1/3+b1/3 - (a-b)/a1/3-b1/3 = (a1/3+b1/3)(a2/3-a1/3*b1/3+b2/3) / (a1/3+b1/3) - (a1/3-b1/3)(a2/3+a1/3*b1/3+b2/3)/(a1/3-b1/3) = (a2/3-a1/3*b1/3+b2/3) - (a2/3+a1/3*b1/3+b2/3) = -2a1/3b1/3 = -2 * 3√ab
