(-4)^73 :2 ^144 - 25 ^12 :5 ^23 =

(-2^2) ^73 :2 ^144 - (5^2) ^12 :5 ^23 =

-2^146 :2 ^144 - 5 ^24 :5 ^23 =

-2^2 - 5 =

-4-5 =

-9

Answer 2

$(-4)^{73}:2^{144}-25^{12}:5^{23}=$

$=-4^{73}:2^{144}-25^{12}:5^{23}$

$=-(2^2)^{73}:2^{144}-(5^2)^{12}:5^{23}$

$=-2^{2\cdot 73}:2^{144}-5^{2\cdot 12}:5^{23}$

$=-2^{146}:2^{144}-5^{24}:5^{23}$

$=-2^{146-144}-5^{24-23}$

$=-2^{2}-5^1$

$=-4-5$

$=\mathbf{-9}$
