化简 (1/2)(53*10^{-3})(34.28571)^2

解答

化简

(\frac{1}{2}) (53 \cdot 1 0^{- 3}) (34.28571)^{2}

\frac{6.2302 E 14}{2.0 E 13}

十进制

31.15101 \dots

求解步骤

(\frac{1}{2}) (53 \cdot 1 0^{- 3}) \cdot 34.2857 1^{2}

使用法则:

(a) = a

(\frac{1}{2}) = \frac{1}{2}

= \frac{1}{2} \cdot 53 \cdot 1 0^{- 3} \cdot 34.2857 1^{2}

1 0^{- 3} = \frac{1}{1000}

= \frac{1}{2} \cdot 53 \cdot \frac{1}{1000} \cdot 34.2857 1^{2}

34.2857 1^{2} = 1175.50991 \dots

= \frac{1}{2} \cdot 53 \cdot \frac{1}{1000} \cdot 1175.50991 \dots

数字相乘:

53 \cdot 1175.50991 \dots = 62302.02524 \dots

= \frac{1}{2} \cdot 62302.02524 \dots \cdot \frac{1}{1000}

= \frac{1}{2} \cdot \frac{1}{1000} \cdot 62302.02524 \dots

62302.02524 \dots = \frac{6.2302 E 14}{10000000000}

= \frac{1}{2} \cdot \frac{1}{1000} \cdot \frac{6.2302 E 14}{10000000000}

\frac{1}{2} \cdot \frac{1}{1000} \cdot \frac{6.2302 E 14}{10000000000} = \frac{6.2302 E 14}{2.0 E 13}

= \frac{6.2302 E 14}{2.0 E 13}
