Question

CẦN GẤP!!!!!

Rút gọn biểu thức

3(2²+1)(2⁴+1)(2⁸+1)(2¹⁶+1)

Cảm ơn mn nhiều

 

Answer 1

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

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

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

\(=\left(2^8-1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(=\left(2^{16}-1\right)\left(2^{16}+1\right)\)

\(=2^{32}-1\)

Answer 2

Đặt : \(P=\left(2^2-1\right)\left(2^2+1\right)\left(2^4+1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

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

\(=\left(2^8-1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

\(=\left(2^{16}-1\right)\left(2^{16}+1\right)\)

\(=2^{32}-1\)

Answer 3

3(2²+1)(2⁴+1)(2⁸+1)(2¹⁶+1

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

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

=\(\left(2^8-1\right)\left(2^8+1\right)\left(2^{16}+1\right)\)

=\(\left(2^{16}-1\right)\left(2^{16}+1\right)\)

=\(2^{32}-1\)

Answer 4

Đặt Q=3(2²+1)(2⁴+1)(2⁸+1)(2¹⁶+1

=(22−1)(22+1)(24+1)(28+1)(216+1)(22−1)(22+1)(24+1)(28+1)(216+1)

=(24−1)(24+1)(28+1)(216+1)(24−1)(24+1)(28+1)(216+1)

=(28−1)(28+1)(216+1)(28−1)(28+1)(216+1)

=(216−1)(216+1)(216−1)(216+1)

=232−1
