solvefor w,36+96=5.625w^2

解答

求解

w, 36 + 96 = 5.625 w^{2}

解答

w = \frac{4 22}{15}, w = - \frac{4 22}{15}

+1

十进制

w = 4.84424 \dots, w = - 4.84424 \dots

求解步骤

36 + 96 = 5.625 w^{2}

交换两边

5.625 w^{2} = 36 + 96

数字相加:

36 + 96 = 132

5.625 w^{2} = 132

在两边乘以

1000

5625 w^{2} = 132000

两边除以

5625

w^{2} = \frac{352}{15}

对于

x^{2} = f (a)

解为

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

w = \frac{352}{15}, w = - \frac{352}{15}

\frac{352}{15} = \frac{4 22}{15}

- \frac{352}{15} = - \frac{4 22}{15}

w = \frac{4 22}{15}, w = - \frac{4 22}{15}

solvefor x,4x^2+9y^2-36z=0

so l v e f or x, 4 x^{2} + 9 y^{2} - 36 z = 0

- x^{2} + 4 x + 36 = 0

4 x^{2} - 17 x + 11 = 0

solvefor x,x^2+y^2+6x-10y+35=0

so l v e f or x, x^{2} + y^{2} + 6 x - 10 y + 35 = 0

900 a = 100 a^{2}
