x10000(2153/315000)^2=29800

解

x \cdot 10000 \cdot (\frac{2153}{315000})^{2} = 29800

x = \frac{295690500000}{4635409}

十進法表記

x = 63789.51673 \dots

解答ステップ

x \cdot 10000 (\frac{2153}{315000})^{2} = 29800

簡素化

10000 (\frac{2153}{315000})^{2} : \frac{4635409}{9922500}

x \frac{4635409}{9922500} = 29800

以下で両辺を乗じる:

9922500

4635409 x = 295690500000

以下で両辺を割る

4635409

x = \frac{295690500000}{4635409}
