0.061 can be represented as the fraction 61/1000. As 61 is a prime number and is not a factor of 1000 then the fraction cannot be simplified and is thus already expressed in its lowest terms.

Take the natural logarithm (ln) of both sides of the equation to cancel the exponent (e). For example, ify=Aexlog transform both sides and apply the rules of logarithms:ln(y)=ln(Aex)ln(y)=ln(A)+ln(ex)ln(y)=ln(A)+xrearrange in terms of x:x=ln(y)-ln(A), or more simplyx=ln(y/A)
2 ln(9) + 2 ln(5) = 2 ln(x) - 3ln(81) + ln(25) = ln(x2) - 37.61332 = ln(x2) - 3ln(x2) = 10.61332ln(x) = 5.30666x = e5.30666 = 201.676 (rounded)

I am interpreting this as: 2ln(x)-2ln(x+1)-ln(x-1)+2ln(5) The rules of logarithmic manipulation that will be used for this are: a*ln(b) = ln(ba) ln(a)-ln(b)=ln(a/b) ln(a)+ln(b)=ln(a*b) Using the first rule, we can perform all of the following operations: 2ln(x) = ln(x2) 2ln(x+1) = ln(x+1)2 2ln(5) = ln(52) = ln(25) From this we can rewrite the problem thus far as: ln(x2)-ln((x+1)2)-ln(x-1)+ln(25) Now using the second and third rules we can do this: ln(x2) - ln((x+1)2) = ln(x2/(x+1)2) ln(x2/(x+1)2)-ln(x-1) = ln((x2/(x+1)2)/(x-1)) = ln(x2/((x+1)2(x-1))) ln(x2/((x+1)2(x-1)))+ln(25) = ln(25x2/((x+1)2(x-1))) So, we have inside of the natural logarithm function a large fraction whose numerator is 25x2 and whose denominator is (x+1)2(x-1). We can expand the denominator through simple binomial multiplication: (x+1)2=x2+2x+1 (x2+2x+1)(x-1) = (x-1)(x2)+(x-1)(2x)+(x-1)(1) = (x3-x2)+(2x2-2x)+(x-1) = x3+x2-x-1 So, in the end, the most simplified form of the original problem that you can get using basic concepts is: ln(25x2/(x3+x2-x-1)) In theory, you could employ partial fraction decomposition to further break down the fraction inside of the natural logarithm function and possibly simplify it further, but this seems to be a problem from an Algebra II class, and partial fraction decomposition is not usually taught at that level in school, so I doubt you will need to break it down any further. If I am making false assumptions and you find out that you do indeed need to use partial fraction decomposition to break it down further, feel free to message me and I will edit this answer.

Use the product rule.y = x lnxy' = x (ln x)' + x' (ln x) = x (1/x) + 1 ln x = 1 + ln xUse the product rule.y = x lnxy' = x (ln x)' + x' (ln x) = x (1/x) + 1 ln x = 1 + ln xUse the product rule.y = x lnxy' = x (ln x)' + x' (ln x) = x (1/x) + 1 ln x = 1 + ln xUse the product rule.y = x lnxy' = x (ln x)' + x' (ln x) = x (1/x) + 1 ln x = 1 + ln x
You can also write this as ln(6 times 4)
2 ln(9) + 2 ln(5) = 2 ln(x) - 3ln(81) + ln(25) = ln(x2) - 37.61332 = ln(x2) - 3ln(x2) = 10.61332ln(x) = 5.30666x = e5.30666 = 201.676 (rounded)
3 ln(x) = ln(3x)ln(x3) = ln(3x)x3 = 3xx2 = 3x = sqrt(3)x = 1.732 (rounded)
