Cuanto es 3√32-2√50+√72

olga55 [171]

Answer:

$3 \sqrt{32} - 2 \sqrt{50} + \sqrt{72} \\ = 3 \sqrt{16 \times 2} - 2 \sqrt{2 \times 25} + \sqrt{36 \times 2} \\ = 3 \times 4 \times \sqrt{2} - 2 \times 5 \times \sqrt{2} + 6 \sqrt{2} \\ = 12 \sqrt{2} - 10 \sqrt{2} + 6 \sqrt{2} \\ = 2 \sqrt{2} + 6 \sqrt{2} \\ = 8 \sqrt{2} \\ thank \: you$
