Webthe answer is -2, 4 is 2^2 and 25=5^2 so 4/25 is the inverse of (5/2)^2 so its (5/2)^-2. to solve this you either have to just see how -2 would make everything line up, or plug it into a … WebMar 13, 2024 · Instead, from 2 x = 3 you get log ( 2 x) = log 3, then by properties of logs you get x log 2 = log 3, so x = ( log 3) / ( log 2). Now you can use any log function your calculator has to get as many decimals of x as your calculator will give you. Just take the log base 2 on both sides. You would get x = l o g 2 3. WebSolution: Use log rule: a = logb ba, then: 1 = ln(e1) = ln(e) → ln(5x− 1) = ln(e) When the logs have the same base: logb f(x) = logb g(x), then: f(x) = g(x) then: ln(5x−1) = ln(e), then: 5x−1 = e → x = e+1 5.

WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2. WebStep-by-Step Examples. Algebra.
