WebFree exponential equation calculator - solve exponential equations step-by-step 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.
WebSolve e 2x = 54. e 2x = 54. ln e 2x = ln 54 . Since the base is e, use the natural logarithm. (If the base were 10, using common logarithms would be better.) ln e 2x = ln 54. 2x = ln 54. Remember that logarithms and exponential functions are inverses. When you have log b b m, the logarithm undoes the exponent, and the result is just m. So ln ...
WebYes, log x a denotes what you need to raise x to the power of to get a. That is, if log x a = b, then a = x b. In particular, x = a 1 / b = a b. holds for some y.
