✔ 最佳答案
27^(-4/8) = 1/27^(1/2)= 1/(3³)^(1/2)
= 1/3^(3/2)
= 1/(3√3)
= √3/(3√3√3)
= √3/9

27^(-4/8)
= 27^(-1/2)
= 屉(27^-1)
= 屉(1/27)
= 屉(1/3 * 1/3 * 1/3)
= ±1/3â(1/3)
= 27^(-1/2)
= 屉(27^-1)
= 屉(1/27)
= 屉(1/3 * 1/3 * 1/3)
= ±1/3â(1/3)

Not sure where your grouping is, so here are the two possibilities:
27^(-4 / 8)
27^(-1 / 2)
1 / (27^(1 / 2))
1 / sqrt(27)
1 / (sqrt(9) * sqrt(3))
1 / (3 * sqrt(3))
sqrt(3) / (3 * sqrt(3) * sqrt(3))
sqrt(3) / (3 * 3)
sqrt(3) / 9
27^-4 / 8
1 / (27^4) / 8
1 / 531441 / 8
1 / (531441 * 8)
1 / 4251528
27^(-4 / 8)
27^(-1 / 2)
1 / (27^(1 / 2))
1 / sqrt(27)
1 / (sqrt(9) * sqrt(3))
1 / (3 * sqrt(3))
sqrt(3) / (3 * sqrt(3) * sqrt(3))
sqrt(3) / (3 * 3)
sqrt(3) / 9
27^-4 / 8
1 / (27^4) / 8
1 / 531441 / 8
1 / (531441 * 8)
1 / 4251528
