1) x = 3
2) x = 100
3) x^2=4
x =2
4) x= 9/5
5) x = 5
6) x = [tex] \sqrt{5}[/tex]
7) x = 2[tex] \sqrt{5} [/tex]
8)x = 2[tex] \sqrt{11} [/tex]
9) x = [tex] \sqrt{15} [/tex] supra [tex] \sqrt{6} [/tex]
10) x = 2[tex] \sqrt{10} [/tex]
11) x = 7 supra [tex] \sqrt{2} [/tex] => x = 7[tex] \sqrt{2} [/tex] supra 2
