Răspuns:
[tex]\bf a + b = 2 \sqrt{6}[/tex]
Explicație pas cu pas:
Saluare!
[tex] \bf 4 - b = 4[/tex]
[tex]\bf 4 = 4 + b[/tex]
[tex]\bf b = 4 - 4[/tex]
[tex] \boxed{\bf b = 0}[/tex]
[tex]\bf{a}^{2} - {b}^{2} = 24[/tex]
[tex]\bf{a}^{2} - 0 = 24[/tex]
[tex]\bf{a}^{2} = 24 \implies a = \sqrt{24} \implies \boxed{ \bf a = 2 \sqrt{6} }[/tex]
[tex]\bf a + b = 2 \sqrt{6} + 0 \implies \boxed{ \bf a + b = 2 \sqrt{6} }[/tex]
