\(A=8^2\cdot324=8^2\cdot18^2=144^2=\left(12^2\right)^2=12^4\)
\(B=27^3\cdot9^4\cdot243=\left(3^3\right)^3\cdot\left(3^2\right)^4\cdot3^5=3^9\cdot3^8\cdot3^5=3^{22}\)
\(C=6^2\cdot36^4\cdot216^2=6^2\cdot\left(6^2\right)^4\cdot\left(6^3\right)^2=6^2\cdot6^8\cdot6^6=6^{16}\)
\(D=3^4\cdot81^2\cdot9^5=3^4\cdot\left(3^4\right)^2\cdot\left(3^2\right)^5=3^4\cdot3^8\cdot3^{10}=3^{22}\)
a. 82. 324 = 26. 220 = 226
b. 273. 94. 243 = 39. 38. 35 = 322
c. 5 .125 . 625 = 5 . 53. 54 = 58
d.10 . 100 . 1000 = 10 . 102. 103 = 106
e. 84. 165. 32 = 212. 220. 25 = 237
f. 274 . 8110 = 312. 340 = 352
a)
49:44=45
178:175=173
210:82=210:24=26
1810:310=1510
275:813=315:312=33
b)106:102=104
59:56=53
410:643=4
225:324=225:220=25
184:94=94
\(4^9:4^4\)
=\(4^{9-4}\)
=\(4^5\)
\(17^8:17^5\)
=\(17^{8-5}\)
= \(17^3\)
\(2^{10}:8^2\)
\(=2^{^{ }10}:\left(2^3\right)^2\)
=\(2^{10}:2^6\)
\(=2^4\)
\(18^{10}:3^{10}\)
=\(\left(18:3\right)^{10}\)
=\(6^{10}\)
b: \(2^{27}=8^9\)
\(3^{18}=9^9\)
mà 8<9
nên \(2^{27}< 3^{18}\)
A= 82 . 324 = (23)2 . (25)4 = 26.220 = 226
\(B=27^3.9^4.81^2\)
\(=\left(3^3\right)^3.\left(3^2\right)^4.\left(3^4\right)^2\)
\(=3^9.3^8.3^8\)
\(=3^{25}\)
A) \(2^{300}=\left(2^3\right)^{100}=8^{100}\)
\(3^{200}=\left(3^2\right)^{100}=9^{100}\)
do \(8^{100}< 9^{100}=>A< B\)
B) \(27^5=\left(3^3\right)^5=3^{15}\)
\(243^3=\left(3^5\right)^3=3^{15}\)
=> \(27^5=243^3\)
