If a = b x c 2 /d 2 what is d = to

\(a\,=\,b\,*\,\frac{c^2}{d^2} \\~\\ a\,=\,\frac{bc^2}{d^2}\)

                                    Multiply both sides of the equation by  d²  .

\(ad^2\,=\,bc^2\)

                                    Divide both sides of the equation by  a  .

\(d^2\,=\,\frac{bc^2}{a}\)

                                    Take the  ± square root  of both sides.

\(d\,=\,\pm\sqrt{\frac{bc^2}{a}}\)
