Question

simplifique a expressão

Answer 1

Oie, Td Bom?!

$= \frac{(10 {}^{a}) {}^{a + 1} }{(10 {}^{a - 2}) {}^{a + 2} }$

$= \frac{10 {}^{a \: . \: (a + 1)} }{10 {}^{(a - 2) \: . \: (a + 2)} }$

$= \frac{10 {}^{a {}^{2} + a} }{10 {}^{a {}^{2} - 4} }$

$= 10 {}^{a {}^{2} + a - (a {}^{2} - 4)}$

$= 10 {}^{a {}^{2} + a - a {}^{2} + 4}$

$= 10 {}^{a + 4}$
