Question

thuộc 7 hđt mở rộng nhá

A= 3(2³+1).(2⁴+1).(2⁸+1)(2¹⁶+1)

các bạn làm hộ với nhanh lên nha , làm tri tiết cho mình nhá mình còn chưa hiểu

Answer 1

\(A=3\left(2^3+1\right)\left(2^4+1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(A=\left(2^2-1\right).9\left(2^4+1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(A=\frac{9}{5}.\left(2^2-1\right)\left(2^2+1\right)\left(2^4+1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(A=\frac{9}{5}.\left(2^4-1\right)\left(2^4+1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(A=\frac{9}{5}.\left(2^8-1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(A=\frac{9}{5}.\left(2^{16}-1\right)\left(2^{16}+1\right)\)

\(A=\frac{9}{5}.\left(2^{32}-1\right)\)
