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

8⁴.16⁵=2¹².2²⁰=2³²

5⁴⁰.125².25³=5⁴⁰.5⁶.5⁶=5⁵²

27⁴.81¹⁰=3¹².3⁴⁰=3⁵²

10³.100⁵.1000⁴=10³.10¹⁰.10¹²=10²⁵

^{Cần chi tiết hơn không?}

\(A=8^4.16^5.32=\left(2^3\right)^4.\left(2^4\right)^5.2^5\)\(=2^{12}.2^{20}.2^5=2^{12+20+5}=2^{37}\)

Vậy \(A=2^{37}\)

\(B=27^4.81^{10}=\left(3^3\right)^4.\left(3^4\right)^{10}=3^{12}.3^{40}=3^{12+40}=3^{52}\)

Vậy \(B=3^{52}\)

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
