What is the value of x given the equation 5 to the power of 1- 2 x equals 0.25 correct to 3 decimal places Please show working out?
51-2x = 0.25 51 * 5-2x = 0.25 5-2x = 0.05 -2x*ln(5) = ln(0.05) x = ln(0.05)/[-2*ln(5)] = 0.931
What logarithmic equation is equivalent to ea equals 35?
hanks to the limitations of the browser through which questions are posted, it is not clear what the question is but, here goes: If the question was ea = 35, then the answer is a = ln(35) where ln are the natural logarithms.
Do any positive real numbers alpha and beta exist such that lnalpha times beta equals lnalpha plus lnbeta and if so what are they?
I assume the question is NOT about ln(a*b) = ln(a) + ln(b) because that is true for all positive real a and b. Instead, you want a solution to ln(a) * b = ln(a) + ln(b) or, ln(a) * (b-1) = ln(b) ln(a) = ln(b)/(b-1) ln(a) = ln[b1/(b-1)] Exponentiating, a = b1/(b-1) For any real number b > 1, a given by the above equation will meet your requirements.
How do you write ln a equals 5.3 in exponential form?
ln(a) = 5.3 a = e5.3

How do you find value ln 2.33?
To find ln 2.33, you need a calculator. It is the solution of the equation e^x = 2.33. ln 2.33 = 0.84586 (using a calculator)
Which exponential equation is equivalent to 3 equals ln x?
3=lnx e^3=x
How do you solve this logarithmic equation ln x equals 5?
In the equation ln(x) = 5, the solution is x = (about) 148.4. To solve, simply raise e to the power of both sides and reduce... ln(x) = 5 eln(x) = e5 x = 148.4
How do you solve this logarithmic equation -3 plus ln x equals 5?
-3 + ln(x) = 5 ln(x) = 8 eln(x) = e8 x = e8 x =~ 2981

What is an accurate interpretation for a value of 0.3 for the regression slope b equals 0.3 for two variables Ln Xi and Ln Yi?
Pi^2 times the square root of 0.3 = Ln Xi for Ln Yi it's a little tougher. (0.3^4 times the value of Ln Xi)/17.2 Hope this helped. (not)
What does e stand for in chemistry in the Clausius-Clapeyron equation?
It stands for euler's number. Its a mathematical constant with the value of approximately 2.72. (Like the value of π(pi) is 3.14, the value of e is 2.72) In the Clausius-Clapeyron equation the "ln"(natural logarithm) is the inverse of "e" e^x = (y) ln(y)=x
If e to the power x equals 0.4634 find x?
the natural log, ln, is the inverse of the exponential. so you can take the natural log of both sides of the equation and you get... ln(e^(x))=ln(.4634) ln(e^(x))=x because ln and e are inverses so we are left with x = ln(.4634) x = -0.769165

Why does lne equal 1?
e = 2.71828183 (approximately)The definition of ln is this: ln x = y when e ^ y = x. It's an inverse property... So ln x means "find out what value y would need to have so that e ^ y equals x" Since e ^ 1 = e, ln e has to equal 1. because in line equation to signify that the task/job is done. This is why it is equal to 1.cause you add them and it just does
How do you solve this logarithmic equation 3x plus 7 equals 20?
To be logarithmic the equation would be, ( otherwise just linear ) 3x + 7 = 20 subtract 7 from each side 3x = 13 now, you know the answer is between x = 2 and x = 3, so I use natural logs both sides ln(3x) = ln(13) as this is a logarithmic operation you can bring down the x in front of the ln sign on the left x ln(3) = ln(13) divideboth sides by ln(3) x = ln(13)/ln(3) ( not ln(13/3)!!!!! ) x = 2.334717519 -------------------------check in original equation 3(2.334717519) + 7 = 20 13 + 7 = 20 20 = 20 --------------checks
