化简 sqrt(6^2+(6\sqrt{3))^2}

解答

化简

6^{2} + (63)^{2}

12

求解步骤

6^{2} + (63)^{2}

6^{2} + (63)^{2} = 144

= 144

因式分解数字:

144 = 1 2^{2}

= 1 2^{2}

使用根式运算法则:

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

1 2^{2} = 12

= 12

e x p an d (x + y) (3 a + 6 t)

e x p an d x^{3} (2 - x) + 5 x (2 - x)

e x p an d - 2 z (7 - 3 z)

s im pl i f y 3 (5 x^{3} + 2 x^{2} - 5) - (x^{2} - 5)

s im pl i f y x^{4} + \frac{1}{2} + \frac{1}{16 x ^{4}}
