a: 6*6*6*6*6=6^5

b: 25*25*25*5=5^2*5^2*5^2*5=5^7

c: 8*2*2*16*4

=2^3*2^2*2^4*2^2

=2^11

d: \(3\cdot3\cdot3\cdot15\cdot5\cdot5\cdot5=15\cdot15\cdot15\cdot15=15^4\)

=(3^3)2:(5^2)3:(7^6:5^6)

=3^6:5^6:(7:5)^6

=(3/5)^6:(7/5)^6

=(3/7)^6

\(=\left(-7\right)^6\)

(-7)⁶

=(-7)⁶

^{yick cho minhf nha}

1) \(9\cdot9\cdot9\cdot9\cdot3\cdot3\)

\(=3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\cdot3\)

\(=3^{10}\)

2) \(8\cdot2\cdot2\cdot2\cdot16\cdot4\)

\(=2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\)

\(=2^{12}\)

3) \(3\cdot3\cdot3\cdot3\cdot5\cdot5\cdot5\cdot5\)

\(=3^4\cdot5^4\)

4) \(25\cdot25\cdot25\cdot5\)

\(=5\cdot5\cdot5\cdot5\cdot5\cdot5\cdot5\)

\(=5^7\)

5) \(7\cdot49\cdot7\cdot7\cdot7\)

\(=7\cdot7\cdot7\cdot7\cdot7\cdot7\)

\(=7^6\)

6) \(8\cdot64\cdot8\cdot64\)

\(=2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\)

\(=2^{18}\)

7) \(2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot4\)

\(=2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2\)

\(=2^8\)

1) 3¹⁰

2) 2¹²

3)3⁴ . 5⁴

4) 5⁷

5) 7⁶

6)8⁶

7) 2⁸.

1) \(...=3^2.3^2.3^2.3^2.3^2=3^{10}\)

2) \(...=2^3.2^3.2^4.2^2=2^{12}\)

3) \(...=3^3.3.5.5.5.5=3^4.5^4\)

4) \(...=5^2.5^2.5^2.5=5^7\)

5) \(...=7.7^2.7.7.7=7^6\)

6) \(...=2^3.\left(2^3\right)^2.2^3.\left(2^3\right)^2=2^3.2^6.2^3.2^6=2^{18}\)

7) \(...=2^6.2^2=2^8\)

ta có :

\(3^3.7^3=\left(3.7\right)^3=21^3\)

3³7³=(3.7)³

Bài 6: 

a: \(2^{27}=8^9\)

\(3^{18}=9^9\)

b: Vì \(8^9< 9^9\)

nên \(2^{27}< 3^{18}\)

= 3^12

đúng chứ?
