d) 45√54 : (-15√3) : (-19)

g) 2supra5√6 : 2supra3√3

Answer 1

d) $45 \sqrt{54}:(-15 \sqrt{3}):(-19)=3 \sqrt{18}* \frac{1}{19}=3*3 \sqrt{2}* \frac{1}{19}= \frac{9 \sqrt{2} }{19}$ ≈ 0.669891

g) $\frac{2}{5 \sqrt{6} } : \frac{2}{3 \sqrt{3} }= \frac{2}{5 \sqrt{6} } * \frac{3 \sqrt{3} }{2 } = \frac{1}{5 \sqrt{2} } *3= \frac{3}{5 \sqrt{2} }= \frac{3 \sqrt{2} }{10}$ ≈ 0.424264
