    \[\frac{x^n}{x^m}=x^{n-m}\]

    so first take care of the constants, \[\frac{8}{4}=\]

    then you have \[\frac{y^7}{y^5}\] since they have the same base you can use the above property so \[\frac{y^7}{y^5}=y^{7-5}\]

    so combine your constant and your variables to get \[2y^{7-5}=2y^2\]

    \[ (18x ^{5}+6x ^{4}-12x ^{3})\div6x ^{2} \] is the q btw it didnt post the powers

    the second equation you need to split everything up into their own fractions

    so \[\frac{18x^5+6x^4-12x^3}{6x^2}=\frac{18x^5}{6x^2}+\frac{6x^4}{6x^2}-\frac{12x^3}{6x^2}\]
