Answer:
1) [tex](3.5)^{2} ; \frac{57}{5}; 6\sqrt{3}; 9.8; \sqrt{75}[/tex]
2) I found their alternate forms. So in the order the #'s were given its 10.4;12.3;8.7;9.8;11.4
3)[tex]x\sqrt{75};9.8x;6x\sqrt{3};\frac{57x}{5}; x(3.5)^{2}[/tex]
4) I chose a negative number to base my calculations off (-2) then found their alternate from's. In order they were given its -20.8; -24.5; -17; -19.6; -22.8
