化简 (2-sqrt(3))(sqrt(2+4\sqrt{6)})

解答

化简

(2 - 3) (2 + 46)

(2 - 3) 2 + 46

十进制

0.92035 \dots

求解步骤

(2 - 3) (2 + 46)

使用法则:

(a) = a

(2 + 46) = 2 + 46

= (2 - 3) 2 + 46

e x p an d (\frac{n}{2} - \frac{2}{n})^{2}

s im pl i f y 10 (lo g_{10} (x) - 5)

e x p an d (2 + 1) (3 + 1)

e x p an d 10 (10 - \frac{e ^{30} - 1}{3 e ^{30}})

e x p an d (x - 3) (x + 3 - 2)
