a/e =sqrt(3+4i)+sqrt(3-4i)

解答

\frac{a}{e} = 3 + 4 i + 3 - 4 i

a = 4 e

十进制

a = 10.87312 \dots

求解步骤

\frac{a}{e} = 3 + 4 i + 3 - 4 i

化简

3 + 4 i + 3 - 4 i : 4

\frac{a}{e} = 4

在两边乘以

e

a = 4 e

so l v e f or f, f (x - 1) = f - 3 x^{3} + 6 x^{2} + 1

so l v e f or c, a^{x} - b^{x} - c = 0

so l v e f or x, 2 (3 x + 4 y) = 4 x + 12 y

\frac{( 3 x - 6 )}{4} - \frac{( x - 1 )}{2} = x

so l v e f or g, g (s) = k \frac{( s ^{2} + 4 )}{( s ^{2} + 2 )}
