因式分解 3-2.3^4+5^2-6-2.3+1

解答

因式分解

3 - 2. 3^{4} + 5^{2} - 6 - 2.3 + 1

- 7.2841

求解步骤

3 - 2. 3^{4} + 5^{2} - 6 - 2.3 + 1

数字相加/相减:

3 - 6 - 2.3 + 1 = - 4.3

= 5^{2} - 2. 3^{4} - 4.3

5^{2} = 25

= 25 - 2. 3^{4} - 4.3

2. 3^{4} = 27.9841

= 25 - 27.9841 - 4.3

数字相减:

25 - 27.9841 - 4.3 = - 7.2841

= - 7.2841
