((2+sqrt(3)))/((2-sqrt(3)))=a+6sqrt(2)

解答

\frac{( 2 + 3 )}{( 2 - 3 )} = a + 62

a = 7 + 43 - 62

十进制

a = 5.44292 \dots

求解步骤

\frac{( 2 + 3 )}{( 2 - 3 )} = a + 62

交换两边

a + 62 = \frac{( 2 + 3 )}{( 2 - 3 )}

a + 62 = \frac{2 + 3}{2 - 3}

将

62

到右边

a = 7 + 43 - 62

(r - r_{0} n) = 0

c = \frac{( 3 \cdot 1 0 ^{2} \cdot 12 \cdot ( 1 0 ^{- 5} ) ^{2} )}{( 15 \cdot 1 0 ^{2} )}

2 b^{2} - 4 p - 78 = 0

so l v e f or a, 1 = - 2 a - 2 c

2 \cdot 3.14 \cdot r \cdot (\frac{40}{360}) = 2.2
