Answer 2

Respuesta:

A)

$\frac{y {}^{9} }{y {}^{3}y {}^{4} } = \frac{y {}^{9} }{y {}^{7} } = y { {}^{9 - 7} }^{} = y {}^{2}$

B)

$(2a {}^{3} b {}^{2} ) {}^{4} = 2 {}^{4} (a {}^{3} ) {}^{4} (b {}^{2} ) {}^{4} = 2 {}^{4} a {}^{3 \times 4} b {}^{2 \times 4} = 16a {}^{12} b {}^{8}$

C)

$( \frac{x {}^{5}y {}^{6} }{x {}^{10}y {}^{8} } ) {}^{ - 2} = ( \frac{x {}^{10}y {}^{8} }{x {}^{5} y {}^{6} } ) {}^{2} = \frac{(x {}^{10}y {}^{8}) {}^{2} }{(x {}^{5} y {}^{6}) {}^{2} } = \frac{x {}^{10 \times 2}y {}^{8 \times 2} }{x {}^{5 \times 2}y {}^{6 \times 2} } = \frac{x {}^{20}y {}^{16} }{x {}^{10}y {}^{12} } = x {}^{10}y {}^{4}$
