e = 2.718
2.718^x + 12(2.718)^-x = 7
it has to do with converting LOG equations, give me a few moments |

You don't need to know what e is to solve this |

5^5 = 5*5*5*5*5
that is a true statement good sir
it means 5 by the power of 5 equals 5 times 5 times 5 times 5 times 5
SALAM. |

e^x-12e^(-x)-1=0
----
e^x -12/e^x -1 = 0
---
Multiply thru by e^x to get:
---
e^(2x) - 12 - e^x = 0
----
This is a quadratic in e^x:
Let e^x = w
Substitute to get:
w^2 -w - 12 = 0
Factor:
(w-4)(w+3) = 0
Positive solution:
w = 4
-----
So, e^x = 4
x = ln(4) |

Newb ln4 is correct but there is another valid value for x |
|
|
There's an example i pulled from a website. it'll show you how to solve one like it. |

sorry gent i forgot to carry the 4 |

The derivative of 7 = nothing.
The answer is nothing. |
