Question

sabendo que x= -1,b= -3 e c= 2 determine
a, xbc^3
b, 10x11b+c
c, xbc
d, x+b+c
e, x+b +xbc=?

Answer 1

Só substituir, x=-1 b=-3 c=2
A) -1.(-3).2^3 = x
X=3.8
X=24

B) mesma coisa
[10.(-1)].[11.(-3)]+2=x
X=-10.(-33)+2
X=330+2
X=332

C) - 1.(-3).2 = x
X= 6

D) - 1+(-3)+2=x
X= - 2

E) - 1+(-3)+[-1.-3.2]=x
X= - 4+6
X= 2
