Odpowiedź:
a) 3*7=21
b)6*8=48
c)9/16 * 6 = 54/16 = 3 3/8
a)
[tex]3( \sqrt{7} {)}^{2} = 3 \times 7 = 21[/tex]
b)
[tex]2 \sqrt{8} \times 3 \sqrt{8} = 6 \sqrt{64} = 6 \times 8 = 48[/tex]
c)
[tex]( \frac{3}{4} \sqrt{6} {)}^{2} = \frac{9}{16} \times 6 = \frac{54}{16} = 3 \frac{6}{16} = 3 \frac{3}{8} [/tex]
