Answer:

Step-by-step explanation:
It is a linear homogeneous differential equation with constant coefficients:
y" + 4y = 0
Its characteristic equation:
r^2+4=0
r1=2i
r2=-2i
We use these roots in order to find the general solution:

Answer:
-2\3
Step-by-step explanation:
Answer:
89
Step-by-step explanation:
2^3=2*2*2=8
3^4=3*3*3*3=9*9=81
