  1.  {x}^{2}   = 7 \ x =  sqrt{7 }  \ x = 2.646
  2. 2 {x}^{2}  = 34 \  {x}^{2}  = 34 div 2 \  {x}^{2}  = 17 \ x =  sqrt{17 }  \ x = 4.123
  3. 3 {x}^{2}  = 138 \  {x}^{2}  = 138 div 3 \  {x}^{2}  = 46 \ x =  sqrt{46}  \ x = 6.782
  4. 0.3 {x}^{2}  = 5.4 \  {x}^{2}  = 5.4 div 0.3 \  {x }^{2}  = 18 \ x =  sqrt{18}   \ x = 4.243
