Question

determinati lungimea muchei cubului care are volumul egal cu:a)8 dam la puterea a 3 b)27 dm la puterea a 3 c)125 m la puterea a 3 d)64 cm la puterea a 3 DAU FUNDA +25 PCTE

Answer 1

a)  
L = ³√8 = 2 dam = 20 m

b)
L = ³√27 = 3 dm = 0,3 m

c)
L = ³√125 = 5 m

d)
L = ³√64 = 4 cm = 0,04 m

Answer 2

v=8dam³=l³=>l=∛8=2dam

v=27dm³=l³=>l=∛27=3dm

v=125m³=l³=>l=∛125=5m

v=64cm³=l³=>l=∛64=4cm
