1/4 a^2=10

解

\frac{1}{4} a^{2} = 10

解

a = 210, a = - 210

+1

十進法表記

a = 6.32455 \dots, a = - 6.32455 \dots

解答ステップ

\frac{1}{4} a^{2} = 10

以下で両辺を乗じる:

4

a^{2} = 40

x^{2} = f (a)

の場合, 解は

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

a = 40, a = - 40

40 = 210

- 40 = - 210

a = 210, a = - 210

(x^2-4x+7)log_{10}(5)+log_{10}(16)=4

(x^{2} - 4 x + 7) lo g_{10} (5) + lo g_{10} (16) = 4

20 x^{2} - 27 x = 14

solvefor x,x^2+y^2+z^2=4

so l v e f or x, x^{2} + y^{2} + z^{2} = 4

(x+5)^2+(x-2)^2=37

(x + 5)^{2} + (x - 2)^{2} = 37

a x^{2} + c = 0
