tolong jawabanya dong soal nomor 2

2.
[tex] \frac{100}{4 \sqrt{10} } \\ = \frac{100}{4 \sqrt{10} } \times \frac{ \sqrt{10} }{ \sqrt{10} }\\ = \frac{100 \sqrt{10} }{4 \sqrt{100} }\\ = \frac{100 \sqrt{10} }{4\times10} \\ = \frac{100 \sqrt{10} }{40} \\ = \frac{5 \sqrt{10} }{2} \\ \bold{= \frac{5}{2} \sqrt{10}} [/tex]

3.
[tex] \frac{4}{4 \sqrt{14} } \\ = \frac{1}{ \sqrt{14} }\\ = \frac{1}{ \sqrt{14} } \times \frac{ \sqrt{14} }{ \sqrt{14} }\\ = \frac{ \sqrt{14} }{ \sqrt{196} }\\ = \frac{ \sqrt{14} }{14}\\ \bold{= \frac{1}{14} \sqrt{14}} [/tex]
