Not sure how to use the disp function and num2str function from this point. Can someone help me out here?

The Richter scale is a measure of the intensity of an earthquake. The energy E(in gigajoules) released by an earthquake is related to the magnitude M on the Richter scale as follows.
E=(10^(-4.6))*(10^(1.5*M))
program the formula for E in a script file.
Use the input function to prompt the use to enter a value of M. The prompt should say "Please enter a Value M on the Richter scale, then press enter". use the disp function and the num2str function to display the numerical value of the energy E with the text "The energy released is:", followed by the value of E, followed by the text "Gigajoules."
So far I have
M=input('Please Enter a Value of M on the Richter scale, then press enter')
E=(10^(-4.6))*(10^(1.5*M))
How do I do this problem from this point?

Hint:
[ 'Pi r^', num2str(3) ]

You look up disp() and num2str() in the help, though personally I think fprintf() is a much better way to display things in the command window.
