Explanation:
#R=((3.8xx10^5)^2)/(5.9xx10^4)#
#color(white)(R)=(14.44xx10^(10))/(5.9xx10^4#
#color(white)(R)=14.44/5.9xx10^((10-4))#
#color(white)(R)=2.447..xx10^6# Since the initial values given for x and y are to 1 decimal place it would be appropriate to return the answer to 1 decimal place.
#rArr~~2.4xx10^6rarr" to 1 decimal place"#
