Question

Tính nhanh: 17×17+17×44+39×17

Answer 1

\(17\times17+17\times44+39\times17=17\left(17+44+39\right)\)

\(=17\times100=1700\)

Answer 2

17x17+17x44+39x17

= 17x(17+44+39)

= 17x(100)

=1700

Answer 3

17 x 17 + 17 x 44 + 39 x 17

= 17 x ( 17 + 44 + 39)

= 17 x 100

=1700

Answer 4

17x17+17x44+39x17

=17.(17+44+39)

=17x100

=1700
