i)$\sqrt{15-4 \sqrt{11$ - $\sqrt{20+6 \sqrt{11$

Answer 1

a) $\sqrt{7-48}$
b) $\sqrt{21+320} = \sqrt{341}$
c)$\sqrt{8-28} d)<u></u>[tex] \sqrt{5+24} = \sqrt{29}$
e)$\sqrt{4+12} = \sqrt{16} =4$
f)$\sqrt{27-200}$
g)$\sqrt{4-12} + \sqrt{16} = \sqrt{4-12} +4$
h)$\sqrt{9+80} + \sqrt{14-180} + \sqrt{89} + \sqrt{14-180}$
i)$\sqrt{15-176} - \sqrt{20+396} = \sqrt{15-176} - \sqrt{416}$
