x=log_{10}(x)

解答

x = lo g_{10} (x)

x \in R 无解

求解步骤

x = lo g_{10} (x)

若

f (x) = g (x)

，则

a^{f (x)} = a^{g (x)}

1 0^{x} = 1 0^{l o g_{10} (x)}

化简

1 0^{l o g_{10} (x)} : x

1 0^{x} = x

解

1 0^{x} = x : x \in R

无解

x \in R 无解

ln (5 x - 1) - ln (x) = 3

lo g_{4} (x - 3) = \frac{1}{2}

lo g_{8} (x) + lo g_{8} (x + 12) = 2

lo g_{2} (x + 4) = 1 + lo g_{2} (x - 3)

ln (3 - x^{2}) = 2 ln (x)
