log_{sqrt(4)}(4)=y

解答

lo g_{4} (4) = y

y = 2

求解步骤

lo g_{4} (4) = y

交换两边

y = lo g_{4} (4)

化简

lo g_{4} (4) : 2

y = 2

36 = - 4 (20 - x)

so l v e f or x, \frac{2}{9} y + 2 x = y - 2 x - 4

\frac{1}{4} (x - 3) + 4 = - 9

so l v e f or j, j (n) = (9 n^{4} + 3 n) (2 n - 4)

\frac{x - a}{b + c} + \frac{x - b}{a + c} + \frac{x - c}{a + b} = 3
