Question

Me ajudem (11^5:11^12)×11^2

Answer 1

Explicação passo-a-passo:

$\sf (11^5\div11^{12})\times11^2$

$\sf =(11^{5-12})\times11^2$

$\sf =11^{-7}\times11^2$

$\sf =11^{-7+2}$

$\sf =11^{-5}$

Answer 2

Oie, Td Bom?!

$= (11 {}^{5} \div 11 {}^{12} ) \: . \: 11 {}^{2}$

$= (11 {}^{5 - 12} ) \: . \: 11 {}^{2}$

$= 11 {}^{ - 7} \: . \: 11 {}^{2}$

$= 11 {}^{ - 7 + 2}$

$= 11 {}^{ - 5}$
