solvefor x,x^2=2^x

解

解く

x, x^{2} = 2^{x}

解

x = - \frac{2 W _{0} ( \frac{l n ( 2 )}{2} )}{ln ( 2 )}, x = 2, x = 4

+1

十進法表記

x = - 0.76666 \dots, x = 2, x = 4

解答ステップ

x^{2} = 2^{x}

equationの両辺を以下の累乗にする:

\frac{1}{2}

(x^{2})^{\frac{1}{2}} = (2^{x})^{\frac{1}{2}}

簡素化

(x^{2})^{\frac{1}{2}} : ∣ x ∣

簡素化

(2^{x})^{\frac{1}{2}} : 2^{\frac{x}{2}}

解く

∣ x ∣ = 2^{\frac{x}{2}} : x = - \frac{2 W _{0} ( \frac{l n ( 2 )}{2} )}{ln ( 2 )} or x = 2 or x = 4

x = - \frac{2 W _{0} ( \frac{l n ( 2 )}{2} )}{ln ( 2 )}, x = 2, x = 4

0.08=(20)/(2^x)

0.08 = \frac{20}{2 ^{x}}

(x-3)^{5x+1}=(x-3)^{x^2-5}

(x - 3)^{5 x + 1} = (x - 3)^{x^{2} - 5}

2 = 1.042 5^{x}

33^{x-2}=17^{8x}
