\\ \sf\longmapsto \dfrac{8^{2x+1}}{64}=8^3

\\ \sf\longmapsto \dfrac{8^{2x+1}}{8^2}=8^3

  • a^m÷a^n=a^{m-n}

\\ \sf\longmapsto 8^{2x+1-2}=8^3

\\ \sf\longmapsto 8^{2x-1}=8^3

\\ \sf\longmapsto 2x-1=3

\\ \sf\longmapsto 2x=3+1

\\ \sf\longmapsto 2x=4

\\ \sf\longmapsto x=\dfrac{4}{2}

\\ \sf\longmapsto x=2

The discriminant of a quadartic equation is 40. What is the nature of the solutions?
o-na [289]

Since the discriminant is positive, this means we have two distinct real solutions.

If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
