    The commands "\bf{x}" or "\mathbf{x}" both produce ##\bf{x}## and ##\mathbf{x}##. The commands "\mathbf{x}^2" and "\mathbf{x^2}" produce ##\mathbf{x}^2## and ##\mathbf{x^2}##, one of which has a bold superscript and the other not. The command \mathbf{x \times \alpha}" produces ##\mathbf{x \times \alpha}## (with bold ##\bf x## but non-bold ##\alpha## and non-bold ##\times##), while "\boldsymbol{x \times \alpha}" produces ##\boldsymbol{x \times \alpha}##, where everything is in bold.
