a, \(8^4.16^5\)

b, \(5^{40}.125^2.25^3\)

c,\(27^4.81^{10}\)

d, \(10^3.100^5.1000^4\)

Bạn ơi mình hỏi là viết các tích của số đó chứ ko phải là ghi ra như vậy

a) \(8^4.16^5\)

\(=\left(2^3\right)^4.\left(2^4\right)^5\\ =2^{3.4}.2^{4.5}\\ =2^{12}.2^{20}\\ =2^{12+20}\\ =2^{32}\)

b) \(5^{40}.125^2.625^3\)

\(=5^{40}.\left(5^3\right)^2.\left(5^4\right)^3\)

\(=5^{40}.5^{3.2}.5^{4.3}\)

\(=5^{40}.5^6.5^{12}\)

\(=5^{40+6+12}\)

\(=5^{58}\)

c) \(27^4.81^{10}\)

\(=\left(3^3\right)^4.\left(3^4\right)^{10}\)

\(=3^{3.4}.3^{4.10}\)

​\(=3^{12}.3^{40}\)​

\(=3^{52}\)

d) \(10^3.100^5.1000^4\)

\(=10^3.\left(10^2\right)^5.\left(10^3\right)^4\)

\(=10^3.10^{2.5}.10^{3.4}\)

\(=10^3.10^{10}.10^{12}\)

\(=10^{3+10+12}\)

\(=10^{25}\)

A

\(5^1.5^3.5^4\)=\(5^{1+3+4}=5^8\)

B

\(10^1.10^2.10^3=10^{1+2+3}=10^6\)

C

\(8^4.16^5.32^1\)

d

\(27^4.81^{10}\)

Thank bạn 

a. = 5 x 5³ x 5⁴ = 5^(1+3+4) = 5⁸

b. = 10 x 10² x 10³ = 10^(1+2+3) = 10⁶

Làm đc từng này thôi nha

Xl bạn

\(a;5\times125\times625=5\times5^3\times5^4=5^8\)

\(d;8^4\times16^5\times32=2^{12}\times2^{20}\times2^5=2^{37}\)

\(5^{40}\times81^{10}=5^{40}\times3^{40}=15^{40}\)

làm sao mà viết được số mũ

a. 8⁴.16⁵ = (2³)⁴. (2⁴)⁵ = 2¹². 2²⁰= 2³²

b. 5⁴⁰.125².625³= 5⁴⁰. (5³)².(5⁴)³= 5⁴⁰.5⁶.5¹²= 5⁵⁸

c. 27⁴.81¹⁰= (3³)⁴.(3⁴)¹⁰= 3¹².3⁴⁰= 3⁵²

d. 10³ . 100⁵ .1000⁴= 10³. (10²)⁵.(10³)⁴= 10³.10¹⁰.10¹²= 10²⁵

\(a,3^7.27^5.81^3\\ =3^7.\left(3^3\right)^5.\left(3^4\right)^3\\ =3^7.3^{15}.3^{12}\\ =3^{34}\\ b,100^6.1000^5.10000^4\\ =100^6.100^{10}.100^{12}\\ =100^{28}\\ c,125^4:5^8\\ =5^{12}:5^8\\ =5^4.\)
