Question

3 : √5 =
√2 : 2√3=
√3+2√2-4√3+5√2=
√75-√27=

Answer 1

Penjelasan dengan langkah-langkah:

[tex]3 \div \sqrt{5} = \frac{3}{ \sqrt{5} } \\ = \frac{3}{ \sqrt{5} } \times \frac{ \sqrt{5} }{ \sqrt{5} } \\ = \frac{3 \sqrt{5} }{ \sqrt{5 \sqrt{5} } } \\ = \frac{3 \sqrt{5} }{5} [/tex]

[tex] \sqrt{2} \div 2 \sqrt{3} \\ = \frac{ \sqrt{2} }{2} \times \sqrt{3} \\ = \frac{ \sqrt{6} }{2} [/tex]

[tex] \sqrt{3} + 2 \sqrt{2} - 4 \sqrt{3} + 5 \sqrt{2} = - 3 \sqrt{3} + 7 \sqrt{2} [/tex]

[tex] \sqrt{75} - \sqrt{27}= 5 \sqrt{3} - 3 \sqrt{3}= 2 \sqrt{3} [/tex]

semoga paham
