Question

calcule os monômios
a) (-10x²y³)+(8x²y³)

b(-6x²y)-(-5y²)​

Answer 1

Oie, tudo bom?

a)

$= ( - 10x {}^{2} y {}^{3} ) + (8x {}^{2} y {}^{3} ) \\ = - 10x {}^{2} y {}^{3} + 8x {}^{2} y {}^{3} \\ = ( - 10 + 8)x {}^{2} y {}^{3} \\ \boxed{ = - 2x {}^{2} y {}^{3} }$

b)

$= ( - 6x {}^{2} y) - ( - 5y {}^{2} ) \\ \boxed{ = -6 x {}^{2}y + 5y {}^{2} }$

Answer 2

Explicação passo-a-passo:

a) (-10x²y³)+(8x²y³) = (-10+8)•x²y³ = -2x²y³

b) (-6x²y)-( -5y²)= -6x²y+5y²
