Question

 viết về dạng lũy thừa 2^7.2^9.3^2

Answer 1

\(2^7\cdot2^9\cdot3^2=2^{7+9}\cdot3^2=2^{16}\cdot3^2\)

chỉ bt chừng đó thôi 😅

Answer 2

2⁷.2⁹.3² = 2⁷⁺⁹.9 = 2¹⁶.9 = 65536.9 = 589824

Answer 3

í, sửa lại 1 tíu

\(=65536\cdot9=589824\)

Answer 4

\(2^7.2^9.3^2=2^{16}.3^2=2^{8.2}.3^2=\left(2^8\right)^2.3^2\)

\(=256^2.3^2=\left(256.3\right)^2=768^2\)

Answer 5

\(2^7.2^9.3^2\)

\(=2^{16}.3^2\)\(=2^{16}.9\)

Dựa vào tính chất 2x² = x² + x² = 2x . 2x , ta có :

\(=9.2^{16}\)\(=18^{16}\)
