There are two square roots of 64 . One is 8 . What is the other?

a) \( \left(-3 x+2 x^{3}-1\right):(x+1) \)

33. The equation of the line perpendicular to the line \( 2 x-y+3=0 \) and which forms with the Cartesian axes in the first quadrant a triangle of area 1 is: A. \( y=\frac{-x-2}{2} \) B. \( y=\frac{2+x}{2} \) C. \( y=\frac{2-x}{2} \) D. \( y=2 x-1 \) E. \( y=-2 x-1 \)

5. Simplify as much as possible. \( \begin{array}{ll}\text { a. }\left(2 x^{3}\right)^{2}\left(3 y^{2}\right) & \text { b. }-5 x+x+10 \\ \text { c. }\left(x^{2}+4 x-1\right)+\left(x^{2}-6 x+11\right) & \text { d. }(-2)^{6} \\ \text { e. } \sqrt{16}+(-16) & \text { f. } 5-(-20) \\ \text { g. }-20-3(-2) & \text { h. } 2 x-3 x-10 x\end{array} \)
