Web8, it will have a unique real triangular root. We know that √ 1+8a is a real number when 1+8a ≥ 0 and a purely imaginary number when 1 +8a<0 (e.g. √ −4 = 2i), and the square roots of real numbers lie on the real and imaginary axes. So if a ≥−1 8, the triangular roots lie along the real axis, whereas if a<− 1 8 then they lie along ... WebAlso, the square of the nth triangular number is the same as the sum of the cubes of the integers 1 to n.. The sum of the all triangular numbers up to the nth triangular number is the nth tetrahedral number,.
