Question

tìm x : 456x -456 + (-207936) x \(\sqrt{25}\) x 2

giúp mình nha

Answer 1

= (-207936) + (-207936) x 5 x 2 

= (-207936) + (-207936) x 10

= (-207936) x (1 + 10)

= (-207936) x 11

= -2287296

k nha!!

Answer 2

456x-456=(-207936)x\(\sqrt{25}\) x2

=> 456(x-1)=-207936x5x2

=> x-1=-2079360:456

=> x-1=-4560

=> x=-4560+1=-4559
