5. a) $\frac{2^{4}}{2^{2}} =2^{2}$

b) $\frac{2^{2}.3^{2}}{6} =\frac{6^{2}}{6} =6$

c) $\frac{2^{3}.5^{2} }{2.5} =\frac{10.2^{2}.5}{10}$=2²·5

d) $\frac{15^{3} }{3.5} =\frac{15^{3}}{15} =15^{2}$

e) $\frac{2^{4}.6}{2^{5} } =\frac{2^{4}.2.3}{2^{5}} =3$

f) $\frac{10^{4}.5^{2}}{2^{3}.5^{3}} =\frac{10^{4}.5^{2}}{10^{3}} =10.5^{2} =250$

7.a) $\frac{4+5+6+7}{5+6} =\frac{22}{11} =2$  ⇒ 2 intregi

b) $\frac{3+4+5+6+7+8}{4+5+6+7} =\frac{33}{22}=1\frac{1}{2}$

c) $\frac{8+9+10+11+12+13+14}{3+4+5+6+7+8} =\frac{77}{33} =2\frac{1}{3}$ ⇒ 2 intregi

d) $\frac{14+15+16+17+18+19}{15+16+17+18} =\frac{99}{66} =1\frac{1}{2}$
