Tính bằng cách phân tích ra :
\(^{3^{99}=\left(3^{33}\right)^3}\)
\(11^{21}=\left(11^7\right)^3\)
Ta có :
\(3^{99}=\left(3^{33}\right)^3\)
\(11^{21}=\left(11^7\right)^3\)
Vì cùng có số mũ là 3
Mà : \(3^{33}>11^7\Rightarrow3^{99}>11^{21}\)
Vậy :\(3^{99}>11^{21}\)

Part 3

6 so
7 or
8 because
9 and
10 more

179 - 58 + 15 + 58 - 75
= 121 + 15 + 58 - 75
= 136 + 58 - 75
= 194 - 75
= 119
( -5 ) * 9 * 2 * 15
= ( -45 ) * 2 *15
= ( -90 ) * 15
= -1350
159 * ( -13 ) - ( -13 ) * 59
= ( -13 ) * ( 159 - 59 )
= ( -13 ) * 100
= -1300
( -109 ) - ( -2 )^3 * ( 6 - 7 )
= ( -109 ) - ( -8 ) * ( -1 )
= ( -109 ) - 8
= -117
