化简 (1+5^2)-16(1/2)^3

解答

化简

(1 + 5^{2}) - 16 (\frac{1}{2})^{3}

24

求解步骤

(1 + 5^{2}) - 16 (\frac{1}{2})^{3}

使用法则:

(a) = a

(1 + 5^{2}) = 1 + 5^{2}

= 1 + 5^{2} - 16 (\frac{1}{2})^{3}

5^{2} = 25

(\frac{1}{2})^{3} = \frac{1}{8}

= 1 + 25 - 16 \cdot \frac{1}{8}

数字相加:

1 + 25 = 26

= 26 - 16 \cdot \frac{1}{8}

16 \cdot \frac{1}{8} = 2

= 26 - 2

数字相减:

26 - 2 = 24

= 24

s im pl i f y (1 + \frac{0.06}{12})^{24}

8 x > - 16

s im pl i f y (4 i + 3) (5 - 2 i)

4 (x + 2)^{2} = 4

s im pl i f y \frac{5}{a ^{2} + 3 a + 2} + \frac{5 a + 1}{a ^{2} + 3 a + 2}
