Find the value of $x$ that satisfy the equation: $3^{11}+3^{11}+3^{11} = 3^x$ I have this question:


$$3^{11}+3^{11}+3^{11} = 3^x$$
    Find the value of $x$



More simply:
$$3^{11}+3^{11}+3^{11}=3\times 3^{11}=3^{12}$$
so the answer you are looking for is $x=12$ (because $x\mapsto 3^x$ is injective).
