化简 ((19)13.5^2)/(32.8523)

解答

化简

\frac{( 19 ) 13. 5 ^{2}}{32.8523}

105.40357 \dots

求解步骤

\frac{( 19 ) \cdot 13. 5 ^{2}}{32.8523}

去除括号:

(a) = a

= \frac{19 \cdot 13. 5 ^{2}}{32.8523}

19 \cdot 13. 5^{2} = 3462.75

= \frac{3462.75}{32.8523}

数字相除:

\frac{3462.75}{32.8523} = 105.40357 \dots

= 105.40357 \dots

3 (x - 7) < 2 (2 x - 1)

- x = - 18

- 2 = - x + x^{2} - 4

\frac{3}{5} x \leq 4

lo g_{2} (x) \geq 1 + lo g_{2} (2 - x)
