Sederhana kan bentuk akar berikut!1. 5√48 – 3√27 + √75 2. (5√3 – √7) (2√3 + √7)​

Jawaban:

16 sqrt{3} \ \ 23 + 3 sqrt{21}

Penjelasan dengan langkah-langkah:

5 sqrt{48} - 3 sqrt{27} + sqrt{75} \ 5 sqrt{ {2}^{4}. 3} - 3 sqrt{ {3}^{3} } + sqrt{3. {5}^{2} } \ 5. {2}^{2} sqrt{3} - 3.3 sqrt{3} + 5 sqrt{3} \ 20 sqrt{3} - 9 sqrt{3} + 5 sqrt{3} = 16 sqrt{3}

(5 sqrt{3} - sqrt{7} )(2 sqrt{3} + sqrt{7} ) \ 10 sqrt{9} - 2 sqrt{21} + 5 sqrt{21} - sqrt{49} \ 10.3 + 3 sqrt{21} - 7 \ 30 - 7 + 3 sqrt{21} \ 23 + 3 sqrt{21}
