\(a,2^5.8^4=2^5.2^{12}=2^{17}\)

\(b,25^6.125^3=5^{12}.5^9=5^{21}\)

\(c,625^5.25^7=5^{20}.5^{14}=5^{34}\)

\(d,12^3.3^3=\left(12.3\right)^3=36^3\)

a) 2⁵ . 8⁴ = 2⁵ . (2³)⁴ = 2⁵ . 2¹² = 2¹⁷

b) 25⁶ . 125³ = (5²)⁶ . (5³)³ = 5^12 _. 5⁹ = 5²¹

c) 625⁵ : 25⁷ = (25²)⁵ : 25⁷ = 25¹⁰ : 25⁷ = 25³

d) 12³ . 3³ = (12 . 3)³ = 36³

Trả lời:

\(a)\)\(2^5.8^4=2^5.\left(2^3\right)^4=2^5.2^{12}=2^{5+12}=2^{17}\)

\(b)\)\(25^6.125^3=\left(5^2\right)^6.\left(5^3\right)^3=5^{12}.5^9=5^{12+9}=5^{21}\)

\(c)\)Chưa rõ đề.

\(d)\)\(12^3.3^3=\left(12.3\right)^3=36^3\)

2⁵.8⁴=2⁵.(2³)⁴=2⁵.2¹²=2¹⁷

25⁶.125³=(5²)⁶.(5³)³=5¹².5⁹=5¹⁷

625⁵:25⁷=(5⁴)⁵:(5²)⁷=5²⁰:2¹⁴=5⁶

Bạn làm sai rồi

25^6.125^3=5^21

thiếu

a) \(2^5.8^4=2^5.\left(2^3\right)^4=2^5.2^{12}=2^{5+12}=5^{17}\)

b) \(25^6.125^3=\left(5^2\right)^6.\left(5^3\right)^3=5^{12}.5^9=5^{12+9}=5^{21}\)

c) \(625^5:25^7=\left(5^4\right)^7:\left(5^2\right)^7=5^{28}:5^{14}=5^{28-14}=5^{14}\)

d) \(12^3.3^3=\left(12.3\right)^3=36^3\)

Dấu chấm là nhân nhé

minh anh sai rồi câu a là 2 mũ 17 mà ghi là 5 mũ 17

a) 2⁵ . 8⁴ = 2⁵ . (2³)⁴ = 2⁵ . 2¹² = 2¹⁷

b) 25⁶ . 125³ = (5²)⁶ . (5³)³ = 5^12 _. 5⁹ = 5²¹

c) 625⁵ : 25⁷ = (25²)⁵ : 25⁷ = 25¹⁰ : 25⁷ = 25³

d) 12³ . 3³ = (12 . 3)³ = 36³

36³ m nha

a) 2⁵ . 8⁴ = 2⁵ . (2³)⁴ = 2⁵ . 2¹² = 2¹⁷

b) 25⁶ . 125³ = (5²)⁶ . (5³)³ = 5¹² . 5⁹ = 5²¹

c) 625³ : 25⁷ = (25²)³ : 25⁷ = 25⁶ : 25⁷ = 0,04

1=1^2 ;125=5^3 ;-125=-5^3; 27=27^1; -27= -27^1

2: 5^2 25^1 

=(12*3)^3

=36^3

12^3 x 3^3 

= ( 12 x 3 )^3

= 36 ^3

\(12^3.3^3=36^3=\left(6^2\right)^3=6^6\)

= 2⁵ . (2³)⁴ = 2⁵⁺¹²= 2¹⁷

= (5²)⁶.(5³)³ = 5¹².5⁹=5¹²⁺⁹= 5²¹

= (5⁴)⁵: (5²)⁷ = 5²⁰:5¹⁴ = 5^{20 - 14}= 5⁶
