The first thing you need to do is click on the button labeled  x y .  This button is in the  first column and the third row of the 12 buttons in the middle of the formula  window.  Note that now the red box where you are going to put the formula is  followed by a square.  The square ( 2 ) is the default value for this button. If some  other time you wanted to change it to another exponent, say a cube ( 3 ), you can click  on the Help button and figure out how. 4.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
