Explicație pas cu pas:
-4^3x[(-5) ^3+13x] =-(2) ^5
4^3x(125+13x)=(-2)^5
-4^3*(-125+13x)=-32
-64(-125+13x)=-32
8000-832x=-32-2
-832x=-32-8000
-832x=-8032
X=251/26
B) - 4^3x[(-5) +13x) =(-2) ^5*x
-4^3*(-5+13x) =(-3)^5*x
-4^3*(-5+13x) =-2^5x
-64(-5+13x) =-2^5
-64(-5+13x)=-32x
320-832x=-32x
-832x=-32x-320
-832x+32x=-320
-800x=-320
X=2/5
C)nu știu cred ca i greșit la pct. C
