Answer 1

a) $\frac{3 \sqrt{4} }{ \sqrt{5}}. \frac{ \sqrt{5} }{ \sqrt{5}} = \frac{3 \sqrt{5.4} }{5} = \frac{3 \sqrt{20} }{5}= \frac{3 \sqrt{2^2.5} }{5}= \frac{3.2 \sqrt{5}}{5} = \frac{6 \sqrt{5} }{5}$

b)$\frac{4}{ \sqrt{8}}. \frac{ \sqrt{8} }{ \sqrt{8}}= \frac{4 \sqrt{8} }{8} = \frac{ \sqrt{8} }{2}$
