a)\(\dfrac{1}{b+2}\)(a²+c)=5      b)k²+(k+1)² ≠(k+2)²

c)8x-7>1                    d)b²-4ac≥0

đ)\(\dfrac{1}{n}\).\(\dfrac{1}{n+1}\).\(\dfrac{1}{n+2}\)<0,01        e)(a-3)(a+5)=0

Answer 1

a) 1/(b+2)*(sqr(a)+c)=5;

b) sqr(k)+sqr(k+1)<>sqr(k+2);

c) (8*x-7)>1;

d) sqr(b)-4*a*c>=0;

đ) (1/n)*(1/(n+1))*(1/(n+2))<0.01;

e) (a-3)*(a+5)=0
