Explicação passo-a-passo:

Monômios semelhantes

$a) \\ 2ab + 7ab - 13ab \\ \\ (2 + 7 - 13)ab \\ \\ - 4ab$

$b) \\ \frac{ (2 {x}^{3} {y}^{2} )}{3} + \frac{7 {x}^{3} {y}^{2} }{4} \\ \\ \frac{8 {x}^{3} {y}^{2} + 21 {x}^{3} {y}^{2} }{12} \\ \\ \frac{29 }{12} {x}^{3} {y}^{2}$

Answer 2

Oie, Td Bom?!

>>> Resolvendo as expressões.

a)

$2ab + 7ab - 13ab$

$(2 + 7 - 13)ab$

$- 4ab$

b)

$\frac{2x {}^{3}y {}^{2} }{3} + \frac{7x {}^{3}y {}^{2} }{4}$

$\frac{4 \: . \: 2x {}^{3} y {}^{2} }{4 \: . \: 3} + \frac{3 \: . \: 7x {}^{3} y {}^{2} }{3 \: . \: 4}$

$\frac{8x {}^{3} y {}^{2} }{12} + \frac{21x {}^{3}y {}^{2} }{12}$

$\frac{8x {}^{3}y {}^{2} + 21x {}^{3} y {}^{2} }{12}$

$\frac{29x {}^{3}y {}^{2} }{12}$

$\frac{29}{12} x {}^{3} y {}^{2}$
