ln(4)r^2=3

解答

ln (4) r^{2} = 3

解答

r = \frac{3}{2 ln ( 2 )}, r = - \frac{3}{2 ln ( 2 )}

+1

十进制

r = 1.47106 \dots, r = - 1.47106 \dots

求解步骤

ln (4) r^{2} = 3

化简

ln (4) : 2 ln (2)

2 ln (2) r^{2} = 3

两边除以

2 ln (2)

r^{2} = \frac{3}{2 ln ( 2 )}

对于

x^{2} = f (a)

解为

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

r = \frac{3}{2 ln ( 2 )}, r = - \frac{3}{2 ln ( 2 )}

流行的例子

2 + \frac{a}{4} = - 1

\frac{3 x + 16}{5} = 2

(1 - y^{2}) = 0

2 = \frac{x + 6}{2}

x^{2} - 2 x - 4 \geq 0
