giúp e vs nha mn, e cần gấp lắm ạ. thanks trc ạ
a, (2^2+1)(2^4+1)(2^8+1)(2^16+1)
b,24(5^2+1)(5^4+1)(5^8+1)(5^16+1)
c,48(7^2+1)(7^4+1)(7^8+1)(7^16+1)
(4-2)^2-16=0
( 2x ^2-3x-1)^ 2 -3( 2x ^2-3x-5 ) -16 = 0
10x^2-6y^2-16 xy
giúp mik dix^2+8x-4y^2+16
2xy - x^2 - y^2 + 16
2/x+2-2x^2+16/x^3+8=5/x^2-2x+4
2xy - x^2 - y^2 + 16
(2x-1)^2-9=16 TÌM x ( 2 trường hợp)
