化简 ((sqrt(-180)))/((sqrt(-10)))

解答

化简

\frac{( - 180 )}{( - 10 )}

32

十进制

4.24264 \dots

求解步骤

\frac{- 180}{- 10}

- 180 = 180 i

= \frac{180 i}{- 10}

- 10 = 10 i

= \frac{180 i}{10 i}

约分:

i

= \frac{180}{10}

分解

180 : 2 \cdot 35

分解

10 : 25

= \frac{2 \cdot 3 5}{2 5}

消掉

\frac{2 \cdot 3 5}{2 5} : 32

= 32

so l v e f or r, A = p i r^{2}

f a c t or x^{3} - 9

so l v e f or A, b 2 A = \frac{1}{2} h (b_{1} + b_{2})

so l v e f or x, e^{l n (x^{2})} - 16 = 0

so l v e f or r, V = \frac{1}{3 p i r ^{2} h}
