Answer 1

$({ \frac{11}{4} )}^{10} \div {( \frac{11}{4} )}^{8}$

$( { \frac{11}{4}) }^{10 - 8}$

$({ \frac{11}{4} )}^{2} = \frac{ {11}^{2} }{ {4}^{2} } = \frac{121}{16}$

Dacă mai ai alte nelămuriri, te astept cu un mesaj privat.

Answer 2

exemplu:

$( \frac{x}{y} ){}^{m} \div ( \frac{x}{y} ) {}^{n} = ( \frac{x}{y}) {}^{m - n} \: \: \: \: m \geqslant n$

$( \frac{11}{4} ) {}^{10 - 8} = ( \frac{11}{4} ) {}^{2} = \frac{121}{16}$
