计算 2a^(-1/3) x [ 0.5a^(1/3) - 2a^(-2/3) ]
计算 2a^(-1/3) x [ 0.5a^(1/3) - 2a^(-2/3) ]
计算 2a^(-1/3) x [ 0.5a^(1/3) - 2a^(-2/3) ]
2a^(-1/3) x [ 0.5a^(1/3) - 2a^(-2/3) ]
=2a^(-1/3)*0.5a^(1/3)-2a^(-1/3)*2a^(-2/3)
=1-4a^(-1/3-2/3)
=1-4/a
2a^(-1/3) x [ 0.5a^(1/3) - 2a^(-2/3) ]
=2a^(-1/3) x 1/2a^(1/3)-2a^(-1/3) x 2a^(-2/3)
=2*1/2a^(-1/3+1/3)-2*2a^(-1/3-2/3)
=a-4/a
希望可以帮到你
