Following is the problem I am trying to solve

x = var('x')

but instead of value of x I am getting

[1633^x == I*40^(1/4)*1600^x, 1633^x == -40^(1/4)*1600^x, 1633^x == -I*40^(1/4)*1600^x, 1633^x == 40^(1/4)*1600^x]

Please advise how to solve this!

What kind of solution do you need (symbolic, numerical, real, complex, ...) ?

If you want a numerical approximation of the unique real solution, you ca try:

sage: f(x) = 10000*(1+(0.0825/4))^(x*4) - 400000
sage: f.find_root(40,50)
