0.373506=(x^2)/(42.1889*0.2727)

解答

0.373506 = \frac{x ^{2}}{42.1889 \cdot 0.2727}

解答

x = \frac{2.14858 E 14}{5.0 E 13}, x = - \frac{2.14858 E 14}{5.0 E 13}

+1

十进制

x = 2.07295 \dots, x = - 2.07295 \dots

求解步骤

0.373506 = \frac{x ^{2}}{42.1889 \cdot 0.2727}

交换两边

\frac{x ^{2}}{42.1889 \cdot 0.2727} = 0.373506

在两边乘以

42.1889 \cdot 0.2727

x^{2} = 4.29715 \dots

对于

x^{2} = f (a)

解为

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

x = 4.29715 \dots, x = - 4.29715 \dots

4.29715 \dots = \frac{2.14858 E 14}{5.0 E 13}

- 4.29715 \dots = - \frac{2.14858 E 14}{5.0 E 13}

x = \frac{2.14858 E 14}{5.0 E 13}, x = - \frac{2.14858 E 14}{5.0 E 13}

因式分解 x^2+3x-154

f a c t or x^{2} + 3 x - 154

因式分解 3x^2+42x+72

f a c t or 3 x^{2} + 42 x + 72

- 4 < 3 x + 2 \leq 8

-29(8x+34)=-170+40x

- 29 (8 x + 34) = - 170 + 40 x
