Question

Tính :

\(\dfrac{16.64.8^2}{4^3.2^5.16}\)

cho mik cách làm nhé

Answer 1

\(\dfrac{16.64.8^2}{4^3.2^5.16}=\dfrac{64.8^2}{4^3.2^5}=\dfrac{64^2}{64.32}=\dfrac{64}{32}=2\)

Answer 2

Đặt :

\(A=\dfrac{16.64.8^2}{4^3.2^5.16}=\dfrac{2^4.2^6.\left(2^3\right)^2}{\left(2^2\right)^3.2^5.2^4}=\dfrac{2^4.2^6.2^6}{2^6.2^5.2^4}=\dfrac{2^{16}}{2^{15}}=2\)

Answer 3

16 . 64 . 8^2 : (4^3 . 2^5 .16)

= 16 . 4^3 . 2^6 : (4^2 . 2^5 . 16)

= 2

Chúc bạn học tốt !!!

Answer 4

\(\dfrac{16.64.8^2}{4^3.2^5.16}\) = \(\dfrac{4^2.2^6.4^3}{4^2.2^5.4^3}\) = \(\dfrac{4^2}{4^2}.\dfrac{2^6}{2^5}.\dfrac{4^3}{4^3}\) = \(1.2.1=2\)

Answer 5

\(\dfrac{16.64.8^2}{4^3.2^516}=\dfrac{16.64.\left(2^3\right)^2}{64.2^5.16}=\dfrac{2^6}{2^5}=2\)
