log_{10}(x)=5-x

解

lo g_{10} (x) = 5 - x

解

x = \frac{W _{0} ( 100000 ln ( 10 ) )}{ln ( 10 )}

+1

十進法表記

x = 4.36046 \dots

解答ステップ

lo g_{10} (x) = 5 - x

f (x) = g (x)

ならば,

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

1 0^{l o g_{10} (x)} = 1 0^{5 - x}

簡素化

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

x = 1 0^{5 - x}

解く

x = 1 0^{5 - x} : x = \frac{W _{0} ( 100000 ln ( 10 ) )}{ln ( 10 )}

x = \frac{W _{0} ( 100000 ln ( 10 ) )}{ln ( 10 )}

解を検算する:

x = \frac{W _{0} ( 100000 ln ( 10 ) )}{ln ( 10 )}

真

解は

x = \frac{W _{0} ( 100000 ln ( 10 ) )}{ln ( 10 )}

log_{6}(7x)+6=8

lo g_{6} (7 x) + 6 = 8

log_{b}(x)=6.92

lo g_{b} (x) = 6.92

3 ln (x + 2) = 2

solvefor x,5=4.75+log_{10}(x)

so l v e f or x, 5 = 4.75 + lo g_{10} (x)

x^{log_{10}(x)}=1000x^2

x^{l o g_{10} (x)} = 1000 x^{2}
