化简 sqrt(x)*sqrt(x+h)

解答

化简

x \cdot x + h

x (x + h)

求解步骤

x x + h

使用根式运算法则:

a b = a \cdot b,

假定

a \geq 0, b \geq 0

x x + h = x (x + h)

= x (x + h)

x^{2} + 6^{2} = 1 0^{2}

lo g_{9} (9^{l o g_{3} (3)}) = x

8 - 8 c = - 6 c

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

f a c t or 288 h - 2 h k^{2}
