1/x =(ln(x)+x)/x

解答

\frac{1}{x} = \frac{ln ( x ) + x}{x}

解答

x = 1

求解步骤

\frac{1}{x} = \frac{ln ( x ) + x}{x}

交换两边

\frac{ln ( x ) + x}{x} = \frac{1}{x}

在两边乘以

x

ln (x) + x = 1

将

x

到右边

ln (x) = 1 - x

若

f (x) = g (x)

，则

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

e^{l n (x)} = e^{1 - x}

化简

e^{l n (x)} : x

x = e^{1 - x}

解

x = e^{1 - x} : x = 1

x = 1

验证解:

x = 1

真

解是

x = 1

2log_{3}(2x-3)+2=3

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

9.1=10log_{10}((4.8)/x)

9.1 = 10 lo g_{10} (\frac{4.8}{x})

solvefor t,log_{5}(t)=u

so l v e f or t, lo g_{5} (t) = u

-3log_{2}(3)=log_{2}(x)

- 3 lo g_{2} (3) = lo g_{2} (x)

log_{10}(x)=875

lo g_{10} (x) = 875
