$E = \dfrac{11.3^{22} . 3^7 - 9^{15}}{(2.3^{14})^2}$
$E = \dfrac{11. 3^{29} - 3^{30}}{2^2 . 3^{28}}$
$E = \dfrac{3^{29} ( 11 - 3)}{2^2.3^{28}}$
$E = \dfrac{3.8}{2^2}$
$E = 6$
$F = \dfrac{4^9. 36 + 64^4}{100 . 16^4}$
$F = \dfrac{2^{20} . 3^2 + 2^{24}}{2^2 . 5^2 . 2^{16}}$
$F = \dfrac{2^{20} . (9 + 2^4)}{2^{18} . 5^2}$
$F = \dfrac{2^{2} .5^2}{5^2}$
$F = 4$
