Question

use laws of exponents to simplify.
5.6^7/4 / 5.6^4/5

Answer 1

Is this the question ?

\[\frac{5.6^\frac{7}{4}}{5.6^\frac{4}{5}}\]

Answer 2

Assuming the above is what you mean ,
then what we need to do in the case of division, is subtract 5.6's exponents:

\[=5.6^{(\frac{7}{4}-\frac{4}{5})}=5.6^{(\frac{35-16}{20})}=5.6^{(\frac{19}{20})}\]
