Learn how to solve exponential equations problems step by step online. Solve the exponential equation 81^x=3. Decompose 81 in it's prime factors. Simplify \left(3^{4}\right)^x using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 4 and n equals x.

2022年10月28日 · The solution set of the equation given as 81^x = 3 is x = 1/4. How to determine the solution set? From the question, the equation of the function is given as. 81^x = 3. Express 81 as an exponent where the base is 3. This means that. 81 = 3⁴. So, we have (3⁴)ˣ = 3. Remove the bracket in the above expression. So, we have. 3⁴ˣ = 3

2020年9月21日 · since 3^4=81. or. apply logarithnm on both sides. log(81^x)=log3. xlog(3^4) =log 3. 4xlog(3)=log 3. log 3 cancels on both sides . 4x=1. hence x=1/4
