3x+12=30
-12   -12

3x=18
/3   /3

x=6

Your answer is 6!

\bf y=\cfrac{5}{2\sqrt[4]{x^3}}\implies y=\cfrac{5}{2}\cdot x^{-\frac{3}{4}}\\\\&#10;-----------------------------\\\\&#10;\cfrac{dy}{dx}=\cfrac{5}{2}\left( -\cfrac{3}{4}x^{-\frac{3}{4}-1} \right)\implies &#10;\cfrac{dy}{dx}=\cfrac{5}{2}\left( -\cfrac{3}{4}x^{-\frac{7}{4}} \right)&#10;\\\\\\&#10; &#10;\cfrac{dy}{dx}=-\cfrac{15}{8}\cdot  x^{-\frac{7}{4}} &#10;\implies &#10;\cfrac{dy}{dx}=-\cfrac{15}{8}\cdot  \cfrac{1}{x^{\frac{7}{4}} }&#10;\\\\\\&#10;

\bf&#10;\cfrac{dy}{dx}=-\cfrac{15}{8x^{\frac{7}{4}}}\implies &#10;\cfrac{dy}{dx}=-\cfrac{15}{8\sqrt[4]{x^7}}\\\\\\ \cfrac{dy}{dx}=-\cfrac{15}{8x\sqrt[4]{x^3}}&#10;
