\(7^2.8^2=\left(7.8\right)^2=56^2\)
\(9^2.2^4=9^2.4^2=\left(9.4\right)^2=36^2\)
\(4^3.7^6=4^3.49^3=\left(49.4\right)^3\)
\(27^4.4^6=\left(27^2\right)^2.64^2=\left(27^2.64\right)^2\)
Bài 1 : Viết tích dưới dạng 1 lũy thừa :
a) 45 . 65 = ( 4 . 6 )5 = 245
b) 72 . 82 = ( 7 . 8 )2 = 562
c) 92 . 24 = ( 32 )2 . 24 = 34 . 24 = ( 3 . 2 )4 = 64
d) 43 . 76 = ( 22 )3 . 76 = 26 . 76 = ( 2 . 7 )6 = 146
e) 274 . 46 = ( 33)4 . ( 22 )6 = 312 . 212 = ( 3 . 2 )12 = 612
