Question

calculați b) radical 20 +radical 45+radical 5 c.radical 6 la puterea 2 +8 la puterea 2 - radical 3 la puterea 4​

Answer 1

Răspuns:

b)

$\sqrt{20} = 2 \sqrt{5}$

$\sqrt{45} = 3 \sqrt{5}$

$2 \sqrt{5} + 3 \sqrt{5} + \sqrt{5} = 6 \sqrt{5}$

c)

$\sqrt{ {6}^{2} + {8}^{2} } - \sqrt{ {3}^{4} } = 10 + 9 = 19$
