scoate factorii de sub radical, va rog, toate 3 ex, dau coroana!!!!!!​

Answer 1

Răspuns:

3 a)

$\sqrt{3} \times \sqrt{3} \times \sqrt{3} \times \sqrt{3 } = 3 \times 3 = 9$

b

$- \sqrt{2} \times( - \sqrt{2} ) = 2$

c

$( - \sqrt{2}) \times ( - \sqrt{2}) \times ( - \sqrt{2}) = 2 \times ( - \sqrt{2} ) = - 2 \sqrt{2}$

d

$5 \sqrt{7} \times 5 \sqrt{7} = 25 \times 7 = 175$

e

$( - 2 \sqrt{3} ) \times ( - 2 \sqrt{3} ) \times ( - 2 \sqrt{3) } = - 24 \sqrt{3}$

f

$- \sqrt{11}$

g

$\sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} \times \sqrt{2} = 2 \times 2 \times 2 \times 2 \times 2 = 32$

h

$(3 \sqrt{2} ) \times (3 \sqrt{2} ) \times (3 \sqrt{2} ) \times (3 \sqrt{2} ) = 9 \times 2 \times 9 \times 2 = 18 \times 18 = 324$

i

$( - 5 \sqrt{3} ) \times ( - 5 \sqrt{3} ) = 25 \times 3 = 75$

j

$(11 \sqrt{11} )\times (11 \sqrt{11} ) = 121 \times 11 = 1331$

k

$( - 5 \sqrt{2} ) \times ( - 5 \sqrt{2} ) \times ( - 5 \sqrt{2} ) =50 \times ( - 5 \sqrt{2} ) = - 250 \sqrt{2}$

l

$( - \sqrt{7} ) \times ( - \sqrt{7}) \times ( - \sqrt{7} ) \times ( - \sqrt{7} ) \times ( - \sqrt{7) } = 7 \times 7 \times ( - \sqrt{7} ) = - 49 \sqrt{7}$
