h^2=100^2+100^2

解

h^{2} = 10 0^{2} + 10 0^{2}

解

h = 1002, h = - 1002

+1

十進法表記

h = 141.42135 \dots, h = - 141.42135 \dots

解答ステップ

h^{2} = 10 0^{2} + 10 0^{2}

簡素化

10 0^{2} + 10 0^{2} : 20000

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

h = 20000, h = - 20000

20000 = 1002

- 20000 = - 1002

h = 1002, h = - 1002

solvefor x,(x+3)^2+(y+1)^2=r^2

so l v e f or x, (x + 3)^{2} + (y + 1)^{2} = r^{2}
