Answer 1

Răspuns:

e)$(2\sqrt{3})^{3} : (\sqrt{2})^{4} =2^{3}(\sqrt{3})^{3}: 4= 24\sqrt{3} :4=6\sqrt{3}$

Am folosit formula: $(ab)^{n}=a^{n} b^{n}$-se distribuie puterea la cei doi factori din paranteza

Answer 2

$(2 \sqrt{3} ) {}^{3} ÷ ( \sqrt{2} ) {}^{4} = (2 \sqrt{3} ) {}^{3} \div 2 {}^{2} = \frac{8 \times 3 \sqrt{3} }{2 {}^{2} } = \frac{2 {}^{3} \times 3 \sqrt{3} }{2 {}^{2} } = 2 \times 3 \sqrt{3} = 6 \sqrt{3}$
