化简 sqrt((1)^2+(\sqrt{3))^2}

解答

化简

(1)^{2} + (3)^{2}

2

求解步骤

1^{2} + (3)^{2}

1^{2} + (3)^{2} = 4

= 4

因式分解数字:

4 = 2^{2}

= 2^{2}

使用根式运算法则:

a^{2} = a, a \geq 0

2^{2} = 2

= 2

s im pl i f y (- 5 c d) (- 3 c^{4} d) - (7 c^{2} d^{2}) (2 c^{3})

s im pl i f y (81 y^{7})^{\frac{1}{3}}

- 3 (x - 2) + 2 < 2 x - 3 - 3 x

144 a = 0.5
