Whаt wоuld be the size оf а blаck hоle (in units of meters) somehow created out of a hot Jupiter exoplanet that was `m` times more massive and 126 times bigger than our own humble Earth?  Please read and comply with the input instructions. Input Instructions:  I have, again, generously given you the final units, so only type in your numerical answer.  Do not round mid-step or carry as many decimal places as you can until the final answer, which should be rounded to two decimal places (i.e. 100.14).  Use standard comma placement if necessary.  Do not include any letters, E, or scientific notation in your final answer.
