Answer 2

Răspuns:

1) a)

$- 5 \sqrt{5}$

b)

$3 \sqrt{10} - 1 \sqrt{10} + 5 \sqrt{10} - 6 \sqrt{10} =$

$(3 - 1 + 5 - 6) \sqrt{10} =$

$1 \sqrt{10} = \sqrt{10}$

c)

$2 \sqrt{7} - 5 \sqrt{7} - 3 \sqrt{7} + 1 \sqrt{7} =$

$(2 - 5 - 3 + 1) \sqrt{7} =$

$- 5 \sqrt{7}$

d)

$(4 - 7 + 2 - 5) \sqrt{3} =$

$- 6 \sqrt{3}$

2) a)

$- 3 \sqrt{3} - 7 \sqrt{2}$

b)

$2 \sqrt{5} - 7 \sqrt{2}$

c)

$3 \sqrt{5} - \sqrt{7}$

d)

$11 \sqrt{7} - 6 \sqrt{3}$

3) a)

$6 \sqrt{2} - 6 \sqrt{3} - 2 {}^{2} \sqrt{2} + 10 \sqrt{3} =$

$6 \sqrt{2} - 6 \sqrt{3} - 4 \sqrt{2} + 10 \sqrt{3} =$

$2 \sqrt{2} + 4 \sqrt{3}$

c)

$6 \sqrt{3} + 9 \sqrt{2} - 6 \sqrt{5} - 10 \sqrt{2} =$

$- \sqrt{2}$

b)

${2}^{2} \times {2}^{2} \sqrt{2} - 15 \sqrt{3} + 4 \sqrt{3} - 10 \sqrt{2} =$

${2}^{4} \sqrt{2} - 15 \sqrt{3} + 4 \sqrt{3} - 10 \sqrt{2} =$

$16 \sqrt{2} - 15 \sqrt{3} + 4 \sqrt{3} - 10 \sqrt{2} =$

$6 \sqrt{2} - 11 \sqrt{3}$

d)

$6 \sqrt{5} - 2 \sqrt{3} - 15 \sqrt{5} + 6 \sqrt{3} =$

$- 9 \sqrt{5} + 4 \sqrt{3}$

Sper că te-am ajutat!
