Answer 1

Răspuns:

a)

$5 \sqrt{6} + 11 \sqrt{6 } - 6 \sqrt{6} = 10 \sqrt{6}$

b)

$12 \sqrt{2} - 4 \sqrt{2} + 5 \sqrt{2} = 13 \sqrt{2}$

c)

$5 \sqrt{7} - 11 \sqrt{7} + 4 \sqrt{7} = - 10 \sqrt{7}$

d)

$12 \sqrt{5} \div 3 \sqrt{5} = 4 \sqrt{5}$

e)

$5 \sqrt{7} \times 3 \sqrt{7} = 15 \sqrt{49 } = 15 \times 7 = 105$

f)

$4 \sqrt{3} \times 3 = 12 \sqrt{3}$
