d=log_{2}(8/(sqrt(d)))

解

d = lo g_{2} (\frac{8}{d})

解

d = \frac{W _{0} ( 128 ln ( 2 ) )}{2 ln ( 2 )}

+1

十進法表記

d = 2.37579 \dots

解答ステップ

d = lo g_{2} (\frac{8}{d})

f (x) = g (x)

ならば,

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

2^{d} = 2^{l o g_{2} (\frac{8}{d})}

簡素化

2^{l o g_{2} (\frac{8}{d})} : \frac{8}{d}

2^{d} = \frac{8}{d}

以下で両辺を乗じる:

d

2^{d} d = \frac{8}{d} d

簡素化

2^{d} d = 8

解く

2^{d} d = 8 : d = \frac{W _{0} ( 128 ln ( 2 ) )}{2 ln ( 2 )}

d = \frac{W _{0} ( 128 ln ( 2 ) )}{2 ln ( 2 )}

解を検算する:

d = \frac{W _{0} ( 128 ln ( 2 ) )}{2 ln ( 2 )}

真

解は

d = \frac{W _{0} ( 128 ln ( 2 ) )}{2 ln ( 2 )}

2ln(x)-(ln(x))^2=0

2 ln (x) - (ln (x))^{2} = 0

log_{4}(x+2)+log_{2}(4)=0

lo g_{4} (x + 2) + lo g_{2} (4) = 0

log_{3}(x-4)+log_{3}(x+6)=1

lo g_{3} (x - 4) + lo g_{3} (x + 6) = 1

log_{x}(1.41)=0.5

lo g_{x} (1.41) = 0.5

-3=20log_{10}(x)

- 3 = 20 lo g_{10} (x)
