log_{10}(x)=3-x

解

lo g_{10} (x) = 3 - x

解

x = \frac{W _{0} ( 1000 ln ( 10 ) )}{ln ( 10 )}

+1

十進法表記

x = 2.58717 \dots

解答ステップ

lo g_{10} (x) = 3 - x

f (x) = g (x)

ならば,

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

1 0^{l o g_{10} (x)} = 1 0^{3 - x}

簡素化

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

x = 1 0^{3 - x}

解く

x = 1 0^{3 - x} : x = \frac{W _{0} ( 1000 ln ( 10 ) )}{ln ( 10 )}

x = \frac{W _{0} ( 1000 ln ( 10 ) )}{ln ( 10 )}

解を検算する:

x = \frac{W _{0} ( 1000 ln ( 10 ) )}{ln ( 10 )}

真

解は

x = \frac{W _{0} ( 1000 ln ( 10 ) )}{ln ( 10 )}

2ln(4x+2)-20=-4

2 ln (4 x + 2) - 20 = - 4

ln(5x-1)=ln(2)+ln(7)

ln (5 x - 1) = ln (2) + ln (7)

log_{4}(x+2)-log_{4}(x)=3

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

(ln(p))/(ln(5))-54=0

\frac{ln ( p )}{ln ( 5 )} - 54 = 0

4 ln (3 x) = - 4
