Question

simplifique as frações algébricas ​

Answer 1

Oie, Td Bom?!

a)

$\frac{8c}{4a} = \frac{2c}{a}$

b)

$\frac{8a {}^{3} x {}^{2} }{10a {}^{2}x {}^{3} } = \frac{8ax {}^{2} }{10x {}^{3} } = \frac{8a}{10x} = \frac{4a}{5x}$

c)

$\frac{7a {}^{3}c }{21ac {}^{5} } = \frac{7a {}^{2} c}{21c {}^{5} } = \frac{a {}^{2} c}{3c {}^{5} } = \frac{a {}^{2} }{3c {}^{4} }$

d)

$\frac{15x {}^{3} b {}^{2} }{45x {}^{2} b {}^{3} } = \frac{15xb {}^{2} }{45b {}^{3} } = \frac{xb {}^{2} }{3b {}^{3} } = \frac{x}{3b}$
