Answer 1

b) $\sqrt{2^{3}+4\sqrt{324} }=\sqrt{8+4*\sqrt{18^{2}} } =\sqrt{8+4*18}=\sqrt{8+72}=\sqrt{80} = 4\sqrt{5}$

c) $\sqrt{16+2\sqrt{289} }=\sqrt{16+2*17}=\sqrt{16+34}=\sqrt{50}=5\sqrt{2}$

d) $\sqrt{36+3\sqrt{256} }=\sqrt{36+3*16}=\sqrt{36+48}=\sqrt{84}=2\sqrt{21}$

e) $\sqrt{33+6\sqrt{361} }=\sqrt{33+6*19}=\sqrt{33+114}=\sqrt{147}= 7\sqrt{3}$

f) $\sqrt{4*3+8\sqrt{441} }=\sqrt{12+8*21} =\sqrt{12+168}=\sqrt{180}= 6\sqrt{5}$

g) $\sqrt{9+9*\sqrt{121} }=\sqrt{9+9*11}=\sqrt{9*(1+11)}=\sqrt{108}= 6\sqrt{3}$

h) $\sqrt{4*6+3*\sqrt{484} }=\sqrt{24+3*22}=\sqrt{24+66}=\sqrt{90}= 3\sqrt{10}$
