-(-3y+8)/(2sqrt(4-y))=0

解答

- \frac{- 3 y + 8}{2 4 - y} = 0

y = \frac{8}{3}

十进制

y = 2.66666 \dots

求解步骤

- \frac{- 3 y + 8}{2 4 - y} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

- 3 y + 8 = 0

解

- 3 y + 8 = 0 : y = \frac{8}{3}

y = \frac{8}{3}

验证解:

y = \frac{8}{3}

真

解是

y = \frac{8}{3}

so l v e f or x, f x = x^{2} - 25

5 p - 3 = 45

2 y + \frac{4}{y} = 5

x + 12 + 8 - x = 6

2 3 x + 2 = - 4
