Question

Calculati cubul numerelor:0,2; 0,4; 0,5; 0,6; 0,7; 0,8 ; repede va roggg

Answer 1

${0.2}^{3} = 0.2 \times 0.2 \times 0.2 = 0.008 \\ {0.4}^{3} = 0.4 \times 0.4 \times 0.4 = 0.064 \\ {0.5}^{3} = 0.5 \times 0.5 \times 0.5 = 0.125 \\ {0.6}^{3} = 0.6 \times 0.6 \times 0.6 = 0.216 \\ {0.7}^{3 } = 0.7 \times 0.7 \times 0.7 = 0.343 \\ {0.8}^{3} = 0.8 \times 0.8 \times 0.8 = 0.512$

Answer 2

convine sa le scriem ca fractii ordinare

0,2³=(1/5)³=1/125

0,4³=(2/5)³=8/125

0,5³=(1/2)³=1/7

0,6³=(6/10)³=(3/5)³=27/127

0,7³=(7/10)³=343/1000=0,343

0,8²=(4/5)³=64/125
