or in this case just cancel

OpenStudy (saifoo.khan):

$\frac{b^{3-2}}{h^{2-1}}$

OpenStudy (saifoo.khan):

$\frac{b}{h}$

OpenStudy (anonymous):

$\frac{\displaystyle\frac{h}{b^2}}{\displaystyle\frac{h^2}{b^3}} = (h\cdot b^{-2})\cdot(h^2\cdot b^{-3})^{-1} = (h \cdot b^{-2})\cdot (h^{-2}b^3) = (h\cdot h^{-2})\cdot(b^3\cdot b^{-2}) = h^{-1}\cdot b = \frac{b}{h}$
