Алгебра номер 3.16 уравнения , пожалуйста срочно надо!

Answer 1

2. ${x}^{2} = 7 \\ x = \sqrt{7 } \\ x = 2.646$
3. $2 {x}^{2} = 34 \\ {x}^{2} = 34 \div 2 \\ {x}^{2} = 17 \\ x = \sqrt{17 } \\ x = 4.123$
4. $3 {x}^{2} = 138 \\ {x}^{2} = 138 \div 3 \\ {x}^{2} = 46 \\ x = \sqrt{46} \\ x = 6.782$
5. $0.3 {x}^{2} = 5.4 \\ {x}^{2} = 5.4 \div 0.3 \\ {x }^{2} = 18 \\ x = \sqrt{18} \\ x = 4.243$
