Question

Rút gọn: A= 7(23+1)(26+1)(212+1)(224+1)

Vũ Minh Tuấn · Accepted Answer

$A=7.\left(2^3+1\right).\left(2^6+1\right).\left(2^{12}+1\right).\left(2^{24}+1\right)$

$A=\left(2^3-1\right).\left(2^3+1\right).\left(2^6+1\right).\left(2^{12}+1\right).\left(2^{24}+1\right)$

$A=\left(2^6-1\right).\left(2^6+1\right).\left(2^{12}+1\right).\left(2^{24}+1\right)$

$A=\left(2^{12}-1\right).\left(2^{12}+1\right).\left(2^{24}+1\right)$

$A=\left(2^{24}-1\right).\left(2^{24}+1\right)$

$A=2^{48}-1.$
