簡約 log_{10}(10^{1/2}(sqrt(0.1)a)^{1/2})-1

解

簡約

lo g_{10} (1 0^{\frac{1}{2}} (0.1 a)^{\frac{1}{2}}) - 1

- \frac{3}{4} + \frac{lo g _{10} ( a )}{2}

解答ステップ

lo g_{10} (1 0^{\frac{1}{2}} (0.1 a)^{\frac{1}{2}}) - 1

簡素化

lo g_{10} (1 0^{\frac{1}{2}} (0.1 a)^{\frac{1}{2}}) : \frac{1}{4} + \frac{lo g _{10} ( a )}{2}

= \frac{1}{4} + \frac{lo g _{10} ( a )}{2} - 1

結合

\frac{1}{4} + \frac{lo g _{10} ( a )}{2} - 1 : - \frac{3}{4} + \frac{lo g _{10} ( a )}{2}

= - \frac{3}{4} + \frac{lo g _{10} ( a )}{2}
