\(a,3^3+3^2-\left(2^7:2^5+7^8:7^7\right)=27+9-\left(2^2+7\right)=36-11=25\)
\(b,27.77+27.27-27=27\left(77+27-1\right)=27.103=2781\)
\(c,52:\left(43-30\right)+144-16=52:13+128=4+128=132\)
\(f,3^2.101-3^2.101^0=3^2\left(101-101^0\right)=9\left(101-1\right)=9.100=900\)

\(=155\)
\(b,=23\times\left(65+35\right)\)- 360
\(=23\times100-360\)
\(=1940\)
\(c,3^3+3^2-\left(2^2+7\right)\)
\(3^3+3^2-\left(4+7\right)\)
=\(3^3+3^2-11\)
=\(27+9-11\)

a) 450 – ( 25 – 10) = 450 – 15
= 435
450 – 25 – 10 = 425 – 10
= 415
b) 180 : 6 : 2 = 30 : 6
= 15
180 : ( 6 : 2 ) = 180 : 3
= 60
c) 410 – (50 +30) = 410 -80
= 330
410 - 50 + 30 = 360 + 30
= 390
d) 16 x (6 : 3) = 16 x 2
= 32
16 x 6 : 3 = 96 : 3
= 32

\(a,2^{300}=\left(2^3\right)^{100}=8^{100}\)
\(3^{200}=\left(3^2\right)^{100}=9^{100}\)
Vì \(8^{100}< 9^{100}\) nên \(2^{300}< 3^{200}\)
\(b,8^5=32768\)
\(6^6=46656\)
Vì \(32768< 46656\) nên \(8^5< 6^6\)
\(c,3^{450}=\left(3^3\right)^{150}=27^{150}\)
\(5^{300}=\left(5^2\right)^{150}=25^{150}\)
Vì \(27^{150}>25^{150}\) nên \(3^{450}>5^{300}\)
