5=sqrt(22+0.06t^2)

解答

5 = 22 + 0.06 t^{2}

解答

t = 52, t = - 52

+1

十进制

t = 7.07106 \dots, t = - 7.07106 \dots

求解步骤

5 = 22 + 0.06 t^{2}

两边进行平方:

25 = 22 + 0.06 t^{2}

25 = 22 + 0.06 t^{2}

解

25 = 22 + 0.06 t^{2} : t = 52, t = - 52

t = 52, t = - 52

验证解:

t = 52

真

, t = - 52

真

解为

t = 52, t = - 52

sqrt(3-x)=sqrt(1+x)-2

3 - x = 1 + x - 2

solvefor x,x^{2/3}=4

so l v e f or x, x^{\frac{2}{3}} = 4

sqrt(x+5)+sqrt(2x+8)=7

x + 5 + 2 x + 8 = 7

solvefor d,T=sqrt(Gd-N^3)

so l v e f or d, T = G d - N^{3}

\sqrt[3]{3-1/x}=-4

3 3 - \frac{1}{x} = - 4
