Applicare la formula: $\frac{a^m}{a^n}$$=a^{\left(m-n\right)}$, dove $a^n=5^2$, $a^m=5^6$, $a=5$, $a^m/a^n=\frac{5^6}{5^2}$, $m=6$ e $n=2$

Applicare la formula: $a\frac{b}{c}$$=\frac{ba}{c}$, dove $a=5^{4}$, $b=7^3$ e $c=7$

Applicare la formula: $a^b$$=a^b$, dove $a=7$, $b=3$ e $a^b=7^3$

Applicare la formula: $ab$$=ab$, dove $ab=343\cdot 625$, $a=343$ e $b=625$

Applicare la formula: $\frac{a}{b}$$=\frac{a}{b}$, dove $a=214375$, $b=7$ e $a/b=\frac{214375}{7}$
