\(B=27^3.9^4.243\)
\(=\left(3^3\right)^3.\left(3^2\right)^4.3^5\)
\(=3^9.3^8.3^5\)
\(=3^{22}\)
Ta có: 27.(-2)3.(-7).(+49)
= 33 . (-2)3 . (-7) . (-7)2
= 33 . (-2)3 . (-7)3 = [3 . (-2) . (-7)]3 = 423
(Lưu ý: 49 = (-7)) . (-7) = (-7)2
Ta có: (-8).(-3)3.(+125)
= (-2)3 . (-3)3 . 53
= [(-2).(-3)]3.53 = 63 . 53
= (6.5)3 = 303
82.324
= (23)2 . (25)4
= 26.220 = 26+20
= 226
b) 815:97
= (92)5:97
= 910:97 = 910-7
= 93
a) 82 . 324 = ( 23)2 . ( 25)4 = 26 . 220 = 226
b) 815 : 97 = ( 34)5 . ( 32)7 = 320 . 314 = 334

a: \(A=\left(2^3\right)^2\cdot\left(2^5\right)^4=2^6\cdot2^{20}=2^{26}\)
b: \(=\left(3^3\right)^3\cdot\left(3^2\right)^4\cdot3^5=3^9\cdot3^8\cdot3^5=3^{22}\)
\(A=8^2.32^4=\left(2^3\right)^2.\left(2^5\right)^4=2^6.2^{20}=2^{26}\)
\(B=27^3.9^4.243=\left(3^3\right)^3.\left(3^2\right)^4.3^5=3^9.3^8.3^5=3^{22}\)
\(A=8^2\cdot32^4\\ =2^6\cdot2^{20}\\ =2^{26}\\ B=27^3\cdot9^4\cdot243\\ =3^9\cdot3^{12}\cdot3^5\\ =3^{26}\)
`A=8^2*32^4=(2^3)^2*(2^5)^4=2^6*2^20=2^26`
`B=27^3*9^4*243=(3^3)^3*(3^2)^4*3^5=3^9*3^8*3^5=3^22`
