化简 (1+(0.1)/2)^2-1

解答

化简

(1 + \frac{0.1}{2})^{2} - 1

\frac{41}{400}

十进制

0.1025

求解步骤

(1 + \frac{0.1}{2})^{2} - 1

(1 + \frac{0.1}{2})^{2} = \frac{441}{400}

= \frac{441}{400} - 1

\frac{441}{400} - 1 = \frac{41}{400}

= \frac{41}{400}

2 x + 3 + 7 x = - 24

36.1 = 117.4 - 4.5 \cdot (15.36 - X)

4 - 3 ∣ x + 8 ∣ = - 2

x + 3 = 3 x - 1

lo g_{4} (10) = x
