Write a Python Code. Write a python code for the problem below.

Specific heat is a property of a given substance that describes how much energy is required to increase the temperature by $1$ degree. The specific heat $(k\frac{J}{k}g-K)$ for dry air can be defined in terms of temperature $($in Kelvin$)$ according to the following equation:

$c_p=0\mathrm{.}99403+1\mathrm{.}671*{10}^{-4}*T+9\mathrm{.}7215*{10}^{-8}*T^2-9\mathrm{.}5838*{10}^{-11}*T^3+1\mathrm{.}9520*{10}^{-14}*T^4$

Find the roots of the equation to determine the temperature that corresponds to a specific heat of $3\mathrm{.}4k\frac{J}{k}g-K.$ Verify the results by plugging back into the original equation.
