$$3\log{x}=\log{x^3}$$ using the property of logarithms that log(ab) = b*log(a)
$$\log{x^2}+\log{x^3}= \log{x^5}$$ using the property that log(a*b) = log(a) + log(b)
Using these, and adding 10 to both sides of the original equation, we have
$$\log{x^5}=10$$
This means that
$$x^5=10^{10}$$
Take the fifth root of both sides
$$x=10^2$$
or $$x=100$$
