(10^{7.24}*0.1)x^2-((0.2)/2)=0

解

(1 0^{7.24} \cdot 0.1) x^{2} - (\frac{0.2}{2}) = 0

解

x = \frac{1}{1 0 ^{7.24}}, x = - \frac{1}{1 0 ^{7.24}}

+1

十進法表記

x = 0.00023 \dots, x = - 0.00023 \dots

解答ステップ

(1 0^{7.24} \cdot 0.1) x^{2} - (\frac{0.2}{2}) = 0

拡張

(1 0^{7.24} \cdot 0.1) x^{2} - (\frac{0.2}{2}) : 1 0^{7.24} \cdot 0.1 x^{2} - \frac{0.2}{2}

1 0^{7.24} \cdot 0.1 x^{2} - \frac{0.2}{2} = 0

\frac{0.2}{2}

を右側に移動します

1 0^{7.24} \cdot 0.1 x^{2} = \frac{0.2}{2}

\frac{0.2}{2} = \frac{2}{20}

1 0^{7.24} \cdot 0.1 x^{2} = \frac{2}{20}

数を約分する:

\frac{2}{20} = \frac{1}{10}

1 0^{7.24} \cdot 0.1 x^{2} = \frac{1}{10}

以下で両辺を割る

1 0^{7.24} \cdot 0.1

x^{2} = \frac{1}{1 0 ^{7.24}}

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

x = \frac{1}{1 0 ^{7.24}}, x = - \frac{1}{1 0 ^{7.24}}

\frac{1}{1 0 ^{7.24}} = \frac{1}{1 0 ^{7.24}}

- \frac{1}{1 0 ^{7.24}} = - \frac{1}{1 0 ^{7.24}}

x = \frac{1}{1 0 ^{7.24}}, x = - \frac{1}{1 0 ^{7.24}}

- 3 x^{2} - 2 x = - 3

L(2000)=2v^2+50v+10

L (2000) = 2 v^{2} + 50 v + 10

x[x+8(x-6)]=7-[5-(2x+5)]

x [x + 8 (x - 6)] = 7 - [5 - (2 x + 5)]

solvefor y,3=e^{-2x}(2y^2+2x^2+2x+1)

so l v e f or y, 3 = e^{- 2 x} (2 y^{2} + 2 x^{2} + 2 x + 1)

solvefor x,3x^2-12m^2=0

so l v e f or x, 3 x^{2} - 12 m^{2} = 0
