Could someone help me solve this please? It's about the

153*1.155^x = 83*1.183^x
1.843*1.155^x = 1.183^x
1.843=1.183^x/1.155^x
1.843=1.024^x
ln(1.843)/ln(1.024)=x
25.78=x

>>346981
Where's the random 1.843 from?

Also, could you try this one too?

>332 x (1.195)^x = 300 x (1.255)^x

>>346983

153/83, you eliminate the two constants first so you only have one left.

>>346983

Also that one works exactly the same way the first one did.
-Divide constants
-Put both ^x terms to one side by division
-a^x * b^x = (a/b)^x
-use log on both sides
-divide so x is alone on one side
-calculate.

>>346988

*a^x / b^x = (a/b)^x of course

>>346988
So what's the answer to the second one? I've got one written down but I think it's wrong. I got over 2 years.

>It's about the practical application of logarithms
153 X 1.155^x = 83 X 1.183^x
log (153 X 1.155^x) = log (83 X 1.183^x)
log 153 X xlog 1.155 = log 83 X xlog1.183
