log_{8}(1/64)=x

解答

lo g_{8} (\frac{1}{64}) = x

x = - 2

求解步骤

lo g_{8} (\frac{1}{64}) = x

交换两边

x = lo g_{8} (\frac{1}{64})

化简

lo g_{8} (\frac{1}{64}) : - 2

x = - 2

f a c t or 2 x^{2} - 15 x + 27

5 - ∣ x ∣ = 15

f a c t or 24 a^{2} b^{5} c^{8} + 30 a^{9} b^{3} - 22 a^{7} b c^{4}

- 14 > 7 v

\frac{x - 1}{x + 1} > 1
