Brainfarted , need help with simple math question. [Solved]

[SSOB]

So basically this :

 

 Basic formula :B= G × g^t

 

50 = 20×1,07^t

t=?

 

what number is t?

 

Thanks , and an explaination would be gratly appreciated as only an anser isn't really going to explain anyting.

Basic formula, doesn't look bloody basic lol

 

Also I have no idea, I really need to get back to school or something and learn this

it's basic for me , again that formula doesn't really have to do anything , it's just for illustrative putpises , for example i could fill in this X= Y×Z^t or something .

Hint: use the properties of the ln function

Well that helps alot...

[Alex780]

Well that helps alot...

Ln (x^t) = t*Ln (x)

[SSOB]

Ln (x^t) = t*Ln (x)

Equation a=b*c^x solved for x x = log(a/b)/log©

This is kind of the hard way i guess but still works tho.

I have no idea actually. are those quadratic equations no? google may have some answers

Nah i already have the anwser that alex780 provided. it's way simpler than using LOG or anything like that.

50/20= 2.5 

log(1.07)(2.5)=13.54284711.

I understand though I used to be able to do them, need to learn again I think
