Odpowiedź:

a). $6*\sqrt{5} *\sqrt{5} =6*\sqrt{25} =6*5=30$

b). $4*\sqrt{6} *\sqrt{6} =4*\sqrt{36} =4*6=24$

c). $2*\sqrt{7} *\sqrt{7} =2*\sqrt{49} =2*7=14$

d). $2*5*\sqrt{3} *\sqrt{3} =10*\sqrt{9} =10*3=30$

e). $-4*3*\sqrt{2} *\sqrt{2} = -12*\sqrt{4} = -12*2= -24$

f). $-3*2*\sqrt{5} *\sqrt{5} = -6*\sqrt{25} = -6*5= -30$

$a) \ 6\sqrt{5}\cdot\sqrt{5} = 6\cdot\sqrt{5}\cdot\sqrt{5} = 6\cdot 5 = 30\\\\b) \ \sqrt{6}\cdot4\sqrt{6} = 4\cdot\sqrt{6}\cdot\sqrt{6} = 4\cdot6 = 24\\\\c) \ \sqrt{7}\cdot2\sqrt{7} = 2\cdot\sqrt{7}\cdot\sqrt{7} = 2\cdot7 = 14\\\\d) \ 2\sqrt{3}\cdot5\sqrt{3} = 2\cdot5\cdot\sqrt{3}\cdot\sqrt{3} = 10\cdot3 = 30\\\\e) \ -4\sqrt{2}\cdot3\sqrt{2} = -4\cdot3\cdot\sqrt{2}\cdot\sqrt{2} = -12\cdot2 = -24\\\\f) \ -3\sqrt{5}\cdot2\sqrt{5} = -3\cdot2\cdot\sqrt{5}\cdot\sqrt{5} = -6\cdot5 = -30$
