Question

calcule o valor de:

(0,4)³+(0,5)²

Answer 1

0,4x0,4x0,4=0,064

0,5 x0,5x0,5 = 0,125

0,125 + 0,064 = 0,189

Answer 2

Resposta:

$(0,4)^{3}+(0,5)^{2}=(\frac{4}{10})^{3}+(\frac{5}{10} )^{2}=(\frac{2}{5})^{3}+(\frac{1}{2} )^{2}=\frac{8}{125} +\frac{1}{4} =\frac{8*4+125}{500} =\frac{157}{500}$
