t_{p}=√(Gh/c^5)

This quantity, t_{p}, is called the Planck time and is thought to be the earliest time, after the creation of the Universe, at which the currently known laws of physics can be applied.

Extra info(I don't know is it going to be helpful for solving this question): The smallest meaning ful measure of length is called the Plank length and is defined in terms of three fundamental constants in nature.

The speed of light c=3.00x10^8 m/s

The gravitational constants G=6.67x10^-11 m^3/kg*s^2

Planck's constant h=6.63x10^-34 kg*m^2/s

Sorry, I have never take physics before, so I have no idea how to solve this question. Thank you for spending your valuable time.
