Is 3^x + 3 a polynomial?
On my sheet it is written as 3 superscript x + 3. Thanks!
Also there is another question thanks! :
A right square pyramid, vertex O, stands on a square base ABCD. The height is 15cm and base length is 10cm. Find:

b. the inclination of a slant edge to the base : 64.76 degrees
c. the inclination of a sloping face to the base : 71.57 degrees
d. the madnitude of the angle between two adjacent sloping faces : I have no idea about this one! Please help it is the angle between the faces?! I can't picture it.
