500=3t+10sqrt(t)+140

解答

500 = 3 t + 10 t + 140

解答

t = \frac{10 ( 113 - 1105 )}{9}

+1

十进制

t = 88.62051 \dots

求解步骤

500 = 3 t + 10 t + 140

去除平方根

9 t^{2} - 2160 t + 129600 = 100 t

解

9 t^{2} - 2160 t + 129600 = 100 t : t = \frac{10 ( 113 + 1105 )}{9}, t = \frac{10 ( 113 - 1105 )}{9}

t = \frac{10 ( 113 + 1105 )}{9}, t = \frac{10 ( 113 - 1105 )}{9}

验证解:

t = \frac{10 ( 113 + 1105 )}{9}

假

, t = \frac{10 ( 113 - 1105 )}{9}

真

解是

t = \frac{10 ( 113 - 1105 )}{9}

(12h-19)^{1/3}+4=9

(12 h - 19)^{\frac{1}{3}} + 4 = 9

sqrt(9x+55)=x+5

9 x + 55 = x + 5

x - 1 + 4 = 0

(x-4)sqrt(3+2x-x^2)=0

(x - 4) 3 + 2 x - x^{2} = 0

2 p^{\frac{3}{2}} = 54
