Maths homework 好簡單

在數學上, 使用相等符號 =, 1等于5, 1 = 5 或者 5 = 1 都是錯誤In mathematical notation (數學表示法)

y is dependable variable and x is independent variable
y is a function of x
The function is given by 5^x (5 is raised to the power of x)
y = 5^x
When x = 1, y = 5^1 = 5
When x = 2, y = 5^2 = 25
When x = 3, y = 5^3 = 125
When x = 4, y = 5^4 = 625
When x = 5, y = 5^5 = 3125
不是這樣寫 5 = 3125
5 不可能 = 3125
Assume y = 5^x
When x = 5, y = 3125 (Answer)


2012-10-13 11:24:52 補充：
y = 5^5
y = 3125 (5 自乘5次, 5乘5乘5乘5乘5 = 3125)

1=5
2=25
3=125
4=625
5=3125

1=5
2=25
3=125
4=625
5=?

答案未就是5=1

好像3+6=6+3 一樣

都是等於9

1.1=5
2.2=25
3.3=125
4.4=625
5.5=1


1. 1=5,5=1

So easy !



1=5


5=1 ~~~~~
