solvefor x,sqrt(x^2+y^2)=r

解

解く

x, x^{2} + y^{2} = r

解

x = r^{2} - y^{2}, x = - r^{2} - y^{2}

解答ステップ

x^{2} + y^{2} = r

両辺を2乗する:

x^{2} + y^{2} = r^{2}

x^{2} + y^{2} = r^{2}

解く

x^{2} + y^{2} = r^{2} : x = r^{2} - y^{2}, x = - r^{2} - y^{2}

x = r^{2} - y^{2}, x = - r^{2} - y^{2}

4/x =sqrt(3x-2)

\frac{4}{x} = 3 x - 2

9x^{4/3}-10x^{2/3}+1=0

9 x^{\frac{4}{3}} - 10 x^{\frac{2}{3}} + 1 = 0

sqrt(-72+17x)=x

- 72 + 17 x = x

2x^{2/3}+x^{1/3}-1=0

2 x^{\frac{2}{3}} + x^{\frac{1}{3}} - 1 = 0

x = 9 x - 10
