Question

PORFAVOR SI NO SE LA SABEN NI SE MOLESTEN DE ONDA
números a = -3, b = -4 y c = -5
Calculá el valor de:
• a + b + c =
• (a + b + c)2=
• ( a + b + c)2=
•a2+ b2+ c2=
a3+ b3+ c3=

Answer 1

Respuesta:

Explicación paso a paso:

a + b + c = -12

$(a+b+c)^{2} =(3 -4 - 5)^{2} = (-12)^{2}=144$$(a+b+c)^{2} =(3 -4 - 5)^{2} = (-12)^{2}=144$

$a^{2}+ b^{2} +c^{2} = (-3)^{2}+ (-4)^{2} +(-5)^{2}=9+16+25=50$

$a^{3}+ b^{3} +c^{3} = (-3)^{3}+ (-4)^{3} +(-5)^{3}=-27-64-125=-216$

Answer 2

Explicación paso a paso:

▪ -3+(-4)+(-5)

= -12

▪(-3+-4+-5)2

= -24

▪(-3)2+(-4)2+(-5)2

= -24

▪(-3)3+(-4)3+(-5)3

= -36
