Question

simplifique:
a)4a+2a-5a+8a
b)x⁴y³z⁶-8x⁴y³z⁶-3x⁴y³z⁶+2x⁴y³z⁶-x⁴y³z⁶

Answer 1

Explicação passo a passo:

a)

$4a+2a - 5a +8a\\\\a(4 +2 -5 +8)\\\\9a$

b)

$x^{4} y^{3} z^{6} - 8 x^{4} y^{3} z^{6} - 3x^{4} y^{3} z^{6}+2x^{4} y^{3} z^{6} - x^{4} y^{3} z^{6}\\\\x^{4} y^{2} z^{6}( 1-8-3+2-1)\\\\-9x^{4} y^{2} z^{6}$
