Question

Tính nhanh :

126^2 - 152 x 126 + 5776

Answer 1

Tính nhanh :

126² - 152 x 126 + 5776

= 126 x 126 - 152 x 126 + 5776

= 126(126-152) + 5776

= -3276 + 5776

= 2500

Answer 2

\(126^2-152.126+5776\)

\(=126.126-152.126+5776\)

\(=126.\left(126-152\right)+5776\)

\(=126.\left(-26\right)+5776\)

\(=\left(-3276\right)+5776\)

\(=2500\)

Answer 3

\(126^2-152.126+5776\)

\(=126.126-152.126+5776\)

\(=126.\left(126-152\right)+5776\)

\(=126.\left(-26\right)+5776\)

\(=-3276+5776\)

\(=2500\)

Answer 4

126² - 152.126+5776

= 126.126 - 152.126+ 5776

=126.(126 - 152)+ 5776

=126.(-26)+5776

= - 3676 + 5776

=2500
