x20000(2153/315000)^2=29800

解

x \cdot 20000 \cdot (\frac{2153}{315000})^{2} = 29800

x = \frac{147845250000}{4635409}

十進法表記

x = 31894.75836 \dots

解答ステップ

x \cdot 20000 (\frac{2153}{315000})^{2} = 29800

簡素化

20000 (\frac{2153}{315000})^{2} : \frac{4635409}{4961250}

x \frac{4635409}{4961250} = 29800

以下で両辺を乗じる:

4961250

4635409 x = 147845250000

以下で両辺を割る

4635409

x = \frac{147845250000}{4635409}
