Giải thích các bước giải:
Đặt `A=3.(4^2+1).(4^4+1).(4^8+1).(4^16+1).(4^32+1)`
`=>5A=(4-1)(4+1).(4^2+1)(4^4+1).(4^8+1).(4^16+1).(4^32+1)`
`=>5A=(4^2-1)(4^2+1)(4^4+1).(4^8+1).(4^16+1).(4^32+1)`
`=>5A=(4^4-1)(4^4+1).(4^8+1).(4^16+1).(4^32+1)`
`=>5A=(4^8-1)(4^8+1)(4^16+1).(4^32+1)`

Đáp án:
Đặt ` A = 3.(4^2+1).(4^4+1).(4^8+1).(4^{16}+1).(4^{32}+1)`
`=> 5A = 15(4^2+1).(4^4+1).(4^8+1).(4^{16}+1).(4^{32}+1)`
`=> 5A = (4^2 – 1)(4^2+1).(4^4+1).(4^8+1).(4^{16}+1).(4^{32}+1)`
`=> 5A = (4^4 – 1)(4^4+1).(4^8+1).(4^{16}+1).(4^{32}+1)`
`=> 5A = (4^8 – 1)(4^8+1).(4^{16}+1).(4^{32}+1)`
`=> 5A = (4^{16} – 1).(4^{16}+1).(4^{32}+1)`
`=> 5A = (4^{32} – 1)(4^{32} + 1)`
`=> 5A = 4^{64} – 1`
`=> A = (4^{64} – 1)/5`
