因式分解 ln(4-4x^2-4y^2)

解答

因式分解

ln (4 - 4 x^{2} - 4 y^{2})

ln (4 (1 - x^{2} - y^{2}))

求解步骤

ln (4 - 4 x^{2} - 4 y^{2})

分解

4 - 4 x^{2} - 4 y^{2} : 4 (1 - x^{2} - y^{2})

= ln (4 (1 - x^{2} - y^{2}))

f a c t or x + x y + x y^{2} - 1 - y - y

f a c t or x^{- 4 a - 6}

f a c t or t^{12} - r^{3} s^{15}

f a c t or \frac{2 \cdot 5 - 4}{5 - 5}

f a c t or 4 (x y)
