title: how to solve folowing equation using python
body: <p>3553200 = 27 × (√n/5)</p>
  <p>3553200 = 1560878×log2(n)/13</p>
  <p>3553200 = 9^n−2</p>
  <p>I have tried the following code:</p>
  <pre><code>from math import sqrt
  from sympy import symbols, solve,Eq
  import math
  exp=27*(sqrt(n)/5)-3553200
  print(solve(exp))
  </code></pre>
  <p>But it gives error:</p>
  <pre><code>TypeError: can't convert expression to float
  
  exp=(1560878*log(n))/13-3553200
  print(solve(exp))
  NameError: name 'log' is not defined
  </code></pre>
