How to convert 115 dB_SPL to Pa?

The decibel is defined as ten times the logarithm of power gain, expressed as power out over power in.
When we work with pressure, rather than power, we use the following modified version of the equation:
dB = 20 log
Prout
Prin
Sound pressure level (dBSPL) is defined by fixing the reference point (Prin) at 20 µPa (2x10-5Pa).
Convert 115 dB SPL to Pa.
(round your answer off to two decimal places, as necessary)
