2)$3^{13}:3^{9}=3^{4}=81$

3)$7^{5}*7^{12} :7^{14} =7^{3} =343$

4)$37^{8}*37^{7} :37 =37^{2} =1369$

5)$(-1\frac{7}{9} )^{10} *(-1\frac{7}{9} )^{10} :(-1\frac{7}{9} )^{20} =(-1\frac{7}{9} )^{0} =1$

7)$(c^{8})^{3} *(c^{3})^{8} =c^{24}*c^{24}=c^{48}$

8)$(-c^{3})^{5} *(-c^{5})^{7} :c^{25}=c^{15}*c^{35}:c^{25}=c^{25}$

9)$c^{34}:(c^{8})^{2} *c^{15}=c^{34}:c^{16}*c^{15}=c^{18}*c^{15}=c^{33}$

10)$12pk^{3} *(-3p^{4}k^{2})=-36p^{5}k^{5}$

11)$0,8a^{2}b^{3}*2,5ab=2a^{3}b^{4}$
