......since the base 7 is the same, when u multiply them, you should add the exponents and keep 7 as it is. That will be 7^4, which in equivalent to ans D(7^2)^2.
It is D parabola because in a double right circular cone the vertex is in the middle of two opposite cones and cutting through the vertex is making parabola.
