a) Ta có : 3111 < 3211 = (25)11 = 255
1714>1614 = (24)14=256
=> 3111 <255<256<1714
=>3111<1714
b)Ta có : 1617 = (24)17 = 268
822 = (23)22 = 266
Vì 268>266 nên 1617 >822
c) Ta có : 10750 <10850= (4.27)50 = 450 .2750 = 2100 . 3150
7375 >7275 = (8.9)75 = 875 . 975 = 2225 . 3150
=> 10750 <2100 .3150 <2225.3150<7375
=> 10750 <7375
d) Ta có : 291 >290 = (25)18 = 3218
535<536 = (52)18 = 2518
Vì 3218 >2518 nên 291 > 535.
e) Ta có : \(\left(\frac{1}{32}\right)^7=\frac{1}{32^7}=\frac{1}{2^{35}}\)
\(\left(\frac{1}{16}\right)^9=\frac{1}{16^9}=\frac{1}{2^{36}}\)
Vì \(\frac{1}{2^{35}}>\frac{1}{2^{36}}\) nên \(\left(\frac{1}{32}\right)^7>\left(\frac{1}{16}\right)^9\)
