$5^{12}.7-5^{11}.10$ $=5^{11}.5.7-5^{11}.10$ $=5^{11}.35-5^{11}.10$ $=5^{11}.(35-10)$ $=5^{11}.25$ $=5^{11}.5^2$ $=5^{11+2}=5^{13}$ Trả lời
5^12.7-5^11.10
=(5^11).35-(5^11).10
=(5^11).(35-10)
=(5^11).15
=5^13
$5^{12}.7-5^{11}.10$
$=5^{11}.5.7-5^{11}.10$
$=5^{11}.35-5^{11}.10$
$=5^{11}.(35-10)$
$=5^{11}.25$
$=5^{11}.5^2$
$=5^{11+2}=5^{13}$
