1262 - 152 x 126 + 5776
= 126 x 126 - 152 x 126 + 5776
= 126(126-152) + 5776
= -3276 + 5776
= 2500
\(126^2-152.126+5776\)
\(=126.126-152.126+5776\)
\(=126.\left(126-152\right)+5776\)
\(=126.\left(-26\right)+5776\)
\(=\left(-3276\right)+5776\)
\(=2500\)
\(126^2-152.126+5776\)
\(=126.126-152.126+5776\)
\(=126.\left(126-152\right)+5776\)
\(=126.\left(-26\right)+5776\)
\(=-3276+5776\)
\(=2500\)
Rất vui vì giúp đc bạn <3
1262 - 152.126+5776
= 126.126 - 152.126+ 5776
=126.(126 - 152)+ 5776
=126.(-26)+5776
= - 3676 + 5776
=2500
