Answer 1

$\frac{3}{5 \sqrt{3} } \times 3 \sqrt{2} = \frac{3 \times 3 \sqrt{2} }{5 \sqrt{3} } = \frac{9 \sqrt{2} }{5 \sqrt{3} } = \frac{9 \sqrt{2} \sqrt{3} }{5 \sqrt{3} \sqrt{3} } = \frac{9 \sqrt{6} }{5 \times 3} = \frac{9 \sqrt{6} }{15} = \frac{3 \sqrt{6} }{5}$

Answer 2

3/5√3 × 3√2 =
=3× 3√2 totul supra/ 5√3=
=9 √2 supra/ 5√3=

rationalizam numitorii fractiei =>
=9× √2 × √3supra/ 5× √3× √3=
=9× √2× √3 supra / 5× 3= simplificam fractia cu 3 =>
=3×√2× √3 supra / 5 =
=3 √6 supra /5
