112 _____ 2√3+8 tolong bantu

Soalnya apakah seperti ini?


[tex] \frac{112}{2 \sqrt{8} + 3} \\ = \frac{112}{2( \sqrt{3} + 4)} \\ = \frac{56}{ \sqrt{3} + 4 } \\ = \frac{56( \sqrt{3} - 4) }{ - 13} \\ = \frac{56 \sqrt{3} - 224 }{ - 13} \\ = \frac{224 - 56 \sqrt{3} }{13} [/tex]


Atau yang ini?

[tex] \frac{112}{2 \sqrt{3 + 8} } \\ = \frac{56}{ \sqrt{3 + 8} } \\ = \frac{56}{ \sqrt{11} } \\ = \frac{56 \sqrt{11} }{11} [/tex]



Semoga membantu
