pi/4 \div pi/4

解答

\frac{π}{4} \div \frac{π}{4}

1

求解步骤

\frac{π}{4} \div \frac{π}{4}

使用分式法则:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{π}{4} \times \frac{4}{π}

分式相乘:

\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}

= \frac{π 4}{4 π}

约分:

π

= \frac{4}{4}

约分:
