Simplify the expression x3/2x5/4\displaystyle {x}^{{{3}/{2}}}\cdot{x}^{{{5}/{4}}}. Assume x>0\displaystyle {x}>{0}.

A) The answer can be written in the form xa\displaystyle {x}^{{a}} where
the exponent a\displaystyle {a} is:   Note: enter the exponent as a reduced fraction or integer.

B) The answer can be written in the form 1xb\displaystyle {\frac{{{1}}}{{{x}^{{b}}}}} where
the exponent b\displaystyle {b} is:   Note: enter the exponent as a reduced fraction or integer.
