frac{(a^5)^6cdot (b^9)^4cdot (a^2b^2)^3}{(b^4)^{10}cdot (a^7)^5}=frac{a^{30}cdot b^{36}cdot a^6cdot b^6}{b^{40}cdot a^{35}}=frac{a^{36}cdot b^{42}}{b^{40}cdot a^{35}}=a^{36-35}cdot b^{42-40}=ab^2

frac{(c^8cdot d^5)^{11}cdot (c^7)^3cdot (d^4)^2}{(d^{31})^2cdot (c^{25})^4}=frac{c^{88}cdot d^{55}cdot c^{21}cdot d^8}{d^{62}cdot c^{100}}=frac{c^{109}cdot d^{63}}{d^{62}cdot c^{100}}=c^{109-100}cdot d^{63-62}=c^9d
