Question

Answer 1

3(22+1)(24+1)(28+1)(216+1)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

Answer 2

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

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

=2^32-1
