Answer 1

$a)$

$4\cdot25^{16}=4\cdot5^{32}\\5^{33}=5\cdot5^{32}\\R:5^{33} > 4\cdot25^{16}$

$b)\\3^{25}=3\cdot3^{24}\\2\cdot27^8=2\cdot(3^3)^8=2\cdot3^{24}\\R:3^{25} > 2\cdot27^8\\c)\\3\cdot16^{21}=3\cdot(2^4)^{21}=3\cdot\22^{84}\\2^{86}=2^2\cdot2^{84}=4\cdot2^{84}\\R:3\cdot16^{21} < 2^{86}$

$d)\\5\cdot81^{11}=5\cdot(3^4)^{11}=5\cdot3^{44}\\3^{45}=3\cdot3^{44}\\R:3^{45} < 5\cdot81^{11}$
