2 ditambah akar 3 ditambah akar 75

Posted by Erwin on September 8, 2015

2 + \sqrt{3} + \sqrt{75}
= 2 + \sqrt{3} + \sqrt{25*3}
= 2 + \sqrt{3} + \sqrt{25} * \sqrt{3}
= 2 +  \sqrt{3} + 5\sqrt{3}
= 2 + 6\sqrt{3}

    2 + akar 3 + akar 75
    = 2 + akar 3 + akar (3×25)
    = 2 + akar 3 + 5 akar 3
    = 2 + 4 akar 3

    Bukannya seperti ini ya?

    Dear Wulanda,

    Betul sekali, sy ada kekeliruan merubah tanda kali menjadi jumlah. Jawaban diatas sy update.

    jadinya mungkin begini ya:

    2 + akar 3 + akar 75
    = 2 + akar 3 + akar (3×25)
    = 2 + akar 3 + 5 akar 3
    = 2 + 6 akar 3

    Terima kasih.
