\( \lim _ { x \rightarrow 0 ^ { + } } \frac { \sqrt[ 3 ] { x \sin ^ { 2 } ( 2 x ) } ( \sqrt { x } - 1 ) } { e ^ { x } - \cos ( 3 x ) } \)

\( x^{2}\times \frac{d}{dx}(y)+y^{2}=0 \)

Solve the equation. Check your solutions. (Enter your answers as a comma-separated list.) \[ \left(x^{2}-x-30\right)^{3 / 2}=125 \] \( x=\square \)

Solve the equation. (Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION.) \[ 4 x^{-4}-5 x^{-2}+1=0 \] \( x=\square \)

\( 3.1 .3 y ^ { 4 } - 81 \)
