Can you please help me solve this equation (-3√7)²+(3√11)²?

Sagot :

(-3√7)^2= 9*7=63  when you raise to the second power, -3 becomes 9
and √7 becomes 7
(3√11)^2=9*11=99
99+63=162

[tex](-3\sqrt{7})^{2} + (3\sqrt{11})^{2} \\(-3\sqrt{7})(-3\sqrt{7}) + (3\sqrt{11})(3\sqrt{11}) \\9\sqrt{49} + 9\sqrt{121} \\9(7) + 9(11) \\63 + 99 \\162[/tex]
