Applicare la formula: $a\log_{b}\left(x\right)$$=-\log_{b}\left(x^{\left|a\right|}\right)$, dove $a=-\frac{1}{2}$, $b=10$ e $x=x+2$

Applicare la formula: $\log_{a}\left(x\right)+\log_{a}\left(y\right)$$=\log_{a}\left(xy\right)$, dove $a=10$, $x=\left(x+4\right)^2$ e $y=\left(x-3\right)^4$

Applicare la formula: $\log_{b}\left(x\right)-\log_{b}\left(y\right)$$=\log_{b}\left(\frac{x}{y}\right)$, dove $b=10$, $x=\left(x+4\right)^2\left(x-3\right)^4$ e $y=\sqrt{x+2}$
