    Do mean that \[\sqrt{2}+\sqrt{5}\div \sqrt{2}-\sqrt{5}\]

    you can multiply it with \[\sqrt{2}.\sqrt{5}\]

    \[so \sqrt{2} \times \sqrt{5} which is \sqrt{10}\]

    Is it supposed to be.. \[\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} -\sqrt{5} }\]

    \[dude when you will multiply then \sqrt{2}*\sqrt{2} will become 2 and vice versa\]

    multiply the fraction by.. \[\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} + \sqrt{5} }\]

    \[(\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} -\sqrt{5} }) * (\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} +\sqrt{5} }) =\]

    no more roots in the denominator after that

    \[=\frac{ 2 + 2\sqrt{2}\sqrt{5} + 5 }{ 2 - 5 }\]

    \[=\frac{ 7 + 2\sqrt{2}\sqrt{5} }{ -3 }\] that about it

    so you just multiply the whole equation by the numerator

    switch the sign in the denominator

    + to -, or, - to +

  25. sohailiftikhar

    yes you can but you have to multiply the both sides

  26. DanJS

    you are just multiplying the fraction by 1

    \[\frac{ \sqrt{2} + \sqrt{5} }{ \sqrt{2} + \sqrt{5} }=1\]

  28. sohailiftikhar

    if you want to remove the numerator then multiply the both sides of equation with it

    \[=7+2\sqrt{2}√5/−3\] is the answer
