Question

Tính nhanh:

312 x 425 + 312 x 574 + 312

Answer 1

\(312\times425+312\times574+312\)

\(=312\times\left(425+574+1\right)\)

\(=312\times1000\)

\(=312000\)

Answer 2

312 × 425 + 312 × 574 + 312

= 312 × (425 + 574 + 1)

= 312 × 1000

= 312000

Answer 3

312x425+312x574+312x1

=312x(425+574+1)

=312x1000

=3120000

Answer 4

$312\times 425+312\times 574+312$

$=312$×425+312×574+312×1

$=312\times \left(425+574+1\right)$

$=312$×(999+1)

$=312\times 1000$

$=312000$

Answer 5

$312\times 425+312\times 574+312$

=312×425+312×574+312×1

$=312\times \left(425+574+1\right)$

$=312\times 1000$

$=312000$
